Abstract
International audience; In this paper, we demonstrate how the development of parallel hardware architectures for turbo decoding can be continued to achieve a throughput of more than 100 Gb/s. A new, fully pipelined architecture shows better error correcting performance for high code rates than the fully parallel approaches known from the literature. This is demonstrated by comparing both architectures for a frame size K = 128 LTE turbo code and a frame size K = 128 turbo code with parity puncture constrained interleaving. To the best of our knowledge, an investigation of the error correcting performance at high code rates of fully parallel decoders is missing fr...
