Abstract

This research aims to analyze the performance of Bose–Chaudhuri–Hocquenghem (BCH) (7,4) coding in a Direct Sequence Spread Spectrum (DSSS) system using Walsh spreading codes under selective fading and Additive White Gaussian Noise (AWGN) channels. The simulation was conducted using MATLAB Simulink by varying the energy-per-bit to noise power spectral density ratio (Eb/No) to evaluate system performance based on the Bit Error Rate (BER). The results show that applying BCH(7,4) significantly reduces the BER, especially at moderate to high Eb/No levels. Furthermore, the combination of Walsh codes with BCH(7,4) demonstrates superior performance compared to systems without error correction. This study highlights the importance of proper selection of spreading and error correction methods in optimizing digital communication performance over multipath fading channels.

Abstract

This study aims to analyze the performance of Bose Chaudhuri–Hocquenghem (BCH) coding (7,4) in a Direct Sequence Spread Spectrum (DSSS) system using Pseudo Noise (PN) spreading code, under frequency selective fading and white Gaussian noise (AWGN) channel conditions. Simulations were performed using MATLAB Simulink to compare the system performance against Bit Error Rate (BER) at various values of bit energy to noise power density (Eb/No). The simulation results show that the use of BCH generally improves system performance by significantly reducing the BER value. At high Eb/No, the performance of PN + BCH is slightly better. This indicates that the effectiveness of signal coding and spreading is strongly influenced by channel conditions and noise levels. Code length, spreading type, and error correction method play an important role in optimizing digital communication performance.
