Interleaving Design Scheme for Parallel Decodable Turbo Codes
摘要
Abstract
Parallel Decodable Turbo Codes(PDTC) increases data throughput, while reduces the decoding performance. This paper analyzes the collision free interleaving condition in PDTC, introduces row column random interleaver and improves it, uses S-random regulation into interleaving, makes the same column(row) position data distance increase to S at least after interleaving. The contrast simulation to row column random interleaver shows that the improved design scheme can raise the data dispersion, enlarge the neighboring data distance in every processor,make the lower code weight better, and increase the bit error rate performance.关键词
