Low-complexity joint source-channel decoding based on variable length encoded Turbo codes
摘要
Abstract
Variable length encoded Turbo codes (VL Turbo codes) with constructed joint decoding plane trellis has better decoding performance than the bit-level decoding algorithm. However the plane trellis is complicated, resulting in a high decoding complexity of VL Turbo codes. We construct a space trellis and propose a low-complexity JSCD approach based on VL Turbo codes. Simulation results show that the proposed approach reduces the decoding complexity by 3.8%, compared to the plane trellis, and the gain of Eb/N0 is about 0. 2dB at SER = 10 -4关键词
