Abstract: In order to improve the throughput and reliability of satellite network,we proposed a satellite communication scheme based on complex field network coding (CFNC).In the scheme,the original message is pre-encoded before transmission.Specifically,it is multiplied by a coding mtrix of parameter space-time codes over complex field.There exi-sts a bijection mapping between the encoded signals and the original ones.Detailed analysis to the performance of throughput and pairwise error probability (PEP) are implemented.The experimental results prove that when the transmission power is kept constant,the throughput of our scheme is 100% higher than routing and 75% higher than pre-vious complex field network coding scheme.Furthermore,the scheme can also be extended to multi-user network communications with more ground stations.Simulation experiments show that PEP approaches the asymptotic curves at high SNR.This supports the theoretical analysis of PEP.
