Abstract

Since telecom businesses have already reached their peak level of revenue, their future is expected to get worse. To save as much money as possible, greater than sixty percent of mobile network operators (MNO) in the worldwide implemented Radio Access Network-Sharing or RAN-Sharing. Earnings before interest, taxes, depreciation, and amortization (EBITDA) pressure and the limited availability of the frequency spectrum are two factors that propel. Spectrum sharing can be one solution to reduce Capital Expenditure and Operational Expenditure operator costs, address spectrum shortages and promote development across the region in Indonesia. With different coverage of underserved areas, the number of assets in the form of BTS and license of frequency spectrum usage are owned by each operator. Research on business impacts for operators needs to be assessed to be able to determine business strategy.

Abstract

The rapid advancement of technology today is evident in fields such as wireless communication. Channel coding plays a crucial role in wireless communication systems because it is essential for mitigating errors and detecting them, thereby ensuring that the system’s performance meets the standards set by 5G technology. This study evaluates the Bit Error Rate (BER) performance in a Wideband Temporal/Statistical Spatial Channel Model (SSCM) using both polar and convolutional codes. The transmission system operates at a frequency of 26 GHz. The simulations for this research were conducted using Binary Phase Shift Keying (BPSK) modulation, with the simulation software utilized for testing. Additionally, the weather parameters for the city of Medan, obtained from the Meteorology, Climatology, and Geophysics Agency (BMKG), including rainfall, air temperature, humidity, and pressure. The power delay profile showed 13 paths, and the BER vulnerability at for the polar code was found to be 3.23%. The results indicate that the polar code outperformed the convolutional code in terms of BER performance, as the polar code achieved a lower Signal-to-Noise Ratio (SNR) compared to the convolutional code
