Abstract

Turbo codes that have attracted a great attention in recent years are applied to wireless communication networks that require variable quality of service and transmit over unknown fading channel. A MAP decoder is the constituent of turbo decoder. In this paper, we propose a high speed architecture of MAP decoder and a new normalization technique, In conclusion, this paper presents the efficient implementation of serial block MAP decoder for turbo codes.
