Abstract : We present a low-complexity architecture designed for the decoding of block turbo codes. In particular we simplify the implementation of Pyndiah's algorithm by not memorizing any of the concurrent codewords generated by the Chase search.
Keywords : Index Terms Block codes Low-complexity design Iterative decoding Turbo codes
