Reduced-search SOVA for block turbo codes

Abstract: In this paper, we propose an efficient reduced-search SOVA (soft output Viterbi algorithm) for block turbo codes. To reduce complexity, the decoder selects a part of the existing paths using ...

Low power SOVA architecture using bi-directional scheme

Abstract: The soft output Viterbi algorithm (SOVA) is the main building block in the turbo coding receiver. A major problem in implementing SOVA is the high complexity and hence high power consumption ...
