Performance of Reed - Solomon Block Turbo Code

11, we present two methods for the constuction codes and in section 111, we describe the soft decoding algorithm and give some results of RS soft decoding. In section IV, we give the soft decision algorithm derived from the theoretical Log-Likelihood-Ratio and in section V we describe the iterative algorithm for decoding RS product codes. Section VI and VI1 are dedicated to simulation results of BER function of signal to noise ratio for different RS turbo codes over Gaussian and Rayleigh channels while in section WI we discuss the results of RS turbo codes.
