In this paper, we address short cycle effects in the distributed low density generator matrix (LDGM) codes. As a codeword is formed from various nodes, the decentralized code construction makes it difficult to eliminate short cycles, resulting in a degraded code performance. To mitigate this effect, we propose a distributed algorithm which can eliminate short cycles within the network. The complexity...
Adaptive network coded cooperation (ANCC) has been proposed as an effective scheme to combine network and channel coding for cooperative wireless networks by matching network-on-graph to code-on-graph. Since the real network consists of randomly faded channels, the link failure and topology change are unavoidable. In this paper, we investigate the performance of ANCC in a real wireless sensor network...
