| 摘 要： | 针对传统协作技术具有的局限性，将一种编码协作技术（基于QC-LDPC码的编码协作）与Alamouti空时码和网络编码技术相结合，提出了一种基于QC-LDPC码的网络编码协作通信技术．仿真结果表明：在系统带宽和发射功率不变的条件下，可以很好地对抗无线信道衰落，在较高的频谱利用率与较低的硬件成本条件下获得较好的编码增益和分集增益．

| Abstract: | In order to overcome the limitations of traditional collaboration technologies, this paper proposes a network coding cooperative communication technology based on QC-LDPC code, which combines the Alamouti orthogonal space4ime codes, network coding technology and coding cooperation technology （coding cooperation based on QC-LDPC code）. The simulation results show that under the condition of keeping system bandwidth and transmission power invariant, this scheme can overcome the radio channel fading and get better coding gain and diversity gain under the higher spectrum utilization efficiency and lower hardware cost conditions. |
