Review of Joint Coding of Channel Coding and Network Coding
摘要
Abstract
Network coding technology can not only improve the throughput and transmission efficiency of the network system,but also make the load more balanced. By employing the joint coding of network coding and channel coding in the Wireless Sensor Network,it can reduce the complexity of data processing in the node and hugely promote the performance of the whole system. Based on the traditional netwok coding model, joint coding can be realized by employing the modulation in the node. Turbo codes and LDPC codes are among those best performing codes and they have some unique advantages so are preferred in the system. The result shows that under the same circumstance of bit error rate 10-4 ,the signal to noise ratio can be saved by 1. 5 dB.关键词
