Implementation of Efficient Turbo Code Encoder-decoder with Max-log-map Algorithm
نویسنده
چکیده
Turbo Codes are very flexible codes and it can be considered as one of the great achievements in the field of communication systems. Turbo Codes have been adopted for wireless digital communication system and they remain unaffected even under heavy traffic situation. The MAX-Log MAP Algorithm which performs necessary computation in Log domain has the capacity to reduce hardware complexity. Major ideas for low power design are employment of a variable number of iterations during decoding process. The encoder was implemented using polynomial method and was found to be less complex. The decoder is implemented in Matlab and then synthesized to measure the performance of the application in BER. The Low complexity of decoding algorithm proposes for efficient Turbo Code to achieve the improvement in hardware implementation which leads to reduction in both area and power consumption. Keywords—Turbo Encoder, Turbo Decoder, MAX-Log-MAP Algorithm.
