Executive Summary

This paper analyzes the performances of Low-Density Parity-Check (LDPC), Reed-Solomon (RS) codes and finds the optimize code rates used for the hybrid combination of both channel coding schemes. These codes are used as the Forward Error Correction (FEC) scheme for image transmission system over several wireless channels. The hybrid FEC scheme consists of LDPC and RS codes. Simulation results show that the performance of image transmission system with LDPC codes is better than the system with RS codes over Rician fading channel. Meanwhile, the system with RS codes has better performance over Rayleigh fading channel. The system with hybrid FEC scheme outperforms the system with LDPC codes as well as the system with RS codes for both fading channels.
