联合多元信道编码调制-网络编码方案
Research of the joint Q-ary channel coding modulation-network coding scheme
摘要
Abstract
In order to make the cooperative relay communication system achieve good tradeoff between effectiveness and reliability, a novel joint Q-ary channel coding modulation-network coding integration design program has been proposed, specifically the Q-ary low-density parity-check codes ( LDPC )-bit interleaved coded modulation ( BICM)-network coding scheme. This scheme combines Q-ary channel coding modulation technology with network coding technology in the relay node, and takes into account the correlation of the sequence of source nodes. A joint iterative correlation decoding algorithm was used to ensure the effectiveness of the system and to improve the relia-bility of the system when decoding. Simulation results demonstrate that, in comparison with the Q-ary LDPC-BICM system without a relay system and uncorrelated signal source, the scheme proposed by this paper can obtain better coding gains and greatly improve the reliability of the system.关键词
