Abstract

MIMO OFDM is the key technology of 4G network system. MIMO-OFDM system enhances the spectrum efficiency and increases the capacity of the system. The implementation of USRP hardware to MIMO OFDM system has been attracted some researchers to conduct the experiments. So we conduct the experiments in a MIMO OFDM system that applies the predistortion technique. In this experiment, we evaluate performances of the predistortion technique by using the artificial neural network. USRP 2920 hardware which is supported by LabVIEW and Phyton software are used in this experiment. OFDM system uses 128 subcarriers to produce an OFDM symbol, and MIMO system uses 2 antennas at transmitter and receiver side. And no obstacles between Tx and Rx, or line of sight transmission scenarios. The performances of the predistortion technique using the artificial neural network algorithm are shown in symbol constellations or Error Vector Magnitude (EVM) at the receiver. And the texts or characters are used as the input of the system. From the experiment results can be seen that the distance between Tx and Rx affects the Error Vector Magnitude (EVM) and predistortion technique produces the Error vector magnitude (EVM) improvement. More shorter the distance between Tx and Rx can decrease distortions of the received signal, At the transmitter side, the performance of predistortion technique is shown as the linearization improvement of the non-linearity power amplifier. Therefore more wider the linear region of power amplifier results the decreasing in band distortion of transmitted signal, and can be seen as the Error Vector Magnitude (EVM) improvement.

Abstract

Internet of Things (IoT) merupakan wujud perkembangan teknologi internet yang akhir-akhir ini menjadi topik perbincangan di kalangan penggiat industri Teknologi Informasi dan Komunikasi (TIK). Masyarakat Indonesia, khususnya para pelajar harus siap menghadapi tantangan tersebut untuk dapat bersaing dengan dunia. Untuk itu pihak penyelenggara pendidikan harus meningkatkan pengetahuan pelajar untuk mengakomodir hal tersebut, sedangkan kurikulum saat ini belum dapat mengakomodir hal tersebut sehingga dibutuhkan kegiatan ekstrakurikuler di luar jam pelajaran sekolah guna meningkatkan pengetahuan tentang teknologi IoT yang saat ini menjadi tren. Salah satu hal yang dapat dilakukan untuk menghadapi tantangan ini yaitu memberikan pembekalan tentang perkembangan teknologi IoT agar para pelajar dapat mempersiapkan diri lebih dini. SMP Al Islah Surabaya adalah salah satu sekolah menengah yang ada di Surabaya. Di sekolah ini, kurikulum yang digunakan masih belum mengakomodir pengetahuan tentang teknologi IoT. Kondisi inilah yang menyebabkan dibutuhkannya pengetahuan dan skill tambahan yang saat ini sedang berkembang sangat penting untuk mereka kuasai, salah satunya adalah tentang IoT. Hal ini yang menjadi dasar pemikiran penulis ingin memberikan skill tambahan kepada siswa SMP Al Islah Surabaya agar memiliki bekal kemampuan lain disamping kemampuan akademik yang mereka terima di sekolah. Penulis memberikan pelatihan IoT, dimana dalam pelaksanaannya kami dibantu oleh mahasiswa Teknik Komputer.

Abstract

The Tire Pressure Monitoring System (TPMS) has evolved into an essential element of contemporary vehicles, playing a pivotal role in enhancing road safety and the overall driving experience. Traditionally, TPMS systems rely on dedicated hardware components for the collection and transmission of tire pressure data to the vehicle's onboard computer and the data is visible only to the driver. In this research, we have developed a wireless communication system between TPMS and a server, enabling tire pressure data to be accessible not only to the driver but also remotely traceable by others. To build a reliable communication system, we utilized a combination of Orthogonal Frequency Division Multiplexing (OFDM) and Convolutional Code technologies. This system is implemented using Software-Defined Radio (SDR) technology. This communication method employs OFDM to enhance data throughput and integrates Convolutional Code to mitigate errors in received data. Consequently, this approach achieves a maximum throughput of 119.19MBps when utilizing the OFDM system alongside 16QAM modulation. The bit error rate for received data without coding stands at 5.77%, but the application of Convolutional Code with a 1/2 code rate effectively reduces this error rate to 3.85%. This system improves the reliability of TPMS communication with the server while also ensuring a consistently high throughput. It enhances road safety and remote monitoring capabilities.

Abstract

There are many motor vehicle accidents on the road, one of the causes being tire blowouts. These accidents occur because drivers continue to drive their vehicles even though the tire pressure and temperature exceed the specified threshold. To address this issue, there is a need for a tire pressure and temperature monitoring system that can be continuously monitored by the driver. If there is a malfunction in the monitoring device on the vehicle dashboard, the driver can be alerted by others who also monitor tire pressure and temperature information remotely. In this study, we developed a tire pressure and temperature monitoring system for vehicles that can be accessed remotely using Internet of Things (IoT) technology. Additionally, we utilized Software Defined Radio (SDR) technology for pressure and temperature data reading. This system successfully monitors tire pressure and temperature changes remotely via computer and smartphone. Based on the test results, the best standard deviation value for tire pressure is 3.54, while the best standard deviation value for tire temperature is 1.72

Abstract

Tire Pressure Monitoring Systems (TPMS) have developed into an essential element in vehicles to improve safety and driving experience. In general, TPMS systems rely on special hardware to collect and transmit tire pressure data to the vehicle's on-board computer and this data can only be viewed by the driver and passengers in the vehicle. In this study, we developed a remote tire pressure and temperature monitoring system using IoT technology. The MQTT protocol facilitated communication between the cloud server and controller, while the system uses Docker container to simplify program integration. The results revealed the optimal standard deviation for tire pressure in hatchback vehicles to be 2.24, and for Multi-Purpose Vehicles (MPVs), it was 2.97. For tire temperature, the best standard deviation in hatchback vehicles was 1.93, compared to 1.05 in MPVs. This system effectively monitors tire pressure and temperature changes in real time, accessible remotely via smartphones and computers.

Abstract

Smart Transportation Systems (STS) leverage Vehicle-to-Vehicle (V2V) communication to enhance road safety, traffic efficiency, and urban mobility. However, ensuring reliable V2V communication remains challenging due to signal power instability, environmental interference, and scalability limitations. This study explores the optimization of V2V communication using Software Defined Radio (SDR) technology, which offers a cost-effective and adaptable approach for real-time signal processing. An SDR-based V2V communication system was developed using GNU Radio and HackRF One, with signal power calibration conducted through comparative measurements involving a Spectrum Analyzer across varying distances (3-15 meters) and environmental conditions. Performance evaluation focused on Bit Error Rate (BER) and Signal-to-Noise Ratio (SNR) under different vehicle speeds (20-40 km/h). Results indicate that increasing distance leads to signal degradation, with BER reaching 36.83% and SNR dropping to -3.17 dB, emphasizing the need for adaptive signal optimization techniques. While SDR-enabled calibration provided accuracy in signal measurements, environmental factors such as multipath interference and atmospheric attenuation significantly impacted communication reliability. Despite its flexibility, the system exhibited high BER and limited communication range, necessitating further enhancements through adaptive modulation schemes, machine learning-based power control, and hybrid 5G-DSRC integration. The study highlights SDR's potential for improving V2V communication while addressing key limitations in urban mobility networks. Future research should focus on enhancing scalability, security, and energy efficiency through advanced signal processing techniques. This study contributes to developing next-generation STS by providing empirical insights into SDR-based V2V communication optimization, supporting safer and more efficient transportation systems.
