Evaluation of Different Coding Methods for Wireless and Satellite Communication

Electronics & Communication Engineering

Decoding of turbo codes is analyzed under the assumption of a maximum-likelihood (ML) list decoder the relative asymptotic gains for turbo codes are larger than those for convolutional codes. a rate ½ convolutional encoder and its corresponding Viterbi decoder was used to improve the decibel gain for a target BER. Finally, Reed Solomon (RS) encoder was serially concatenated with the convolutional encoder and BER performance was obtained. Since in mobile wireless access the location of the end user is changing and different users may be moving at different speeds so the RS encoder will further improve the system performance
