采用LDPC码的结构研究了协作分集网络中的网络编码构造，并把它拓展到多跳网络中。
This paper introduces a class of network coding based on LDPC code for a cooperative network and extends it to multi-hop network.
在无线衰落信道环境中，协作中继是一种增加额外分集增益的有效方法，而网络编码可以用来提高网络吞吐量。
In the wireless fading channel environment, cooperative relaying is an effective way to increase additional diversity gain, and network coding can be used to increase network throughput.
由于中继节点的参与，该协议可充分利用多用户协作的空间分集和出错重传所带来的时间分集和编码增益。
As the relay node's involvement, the agreement can take full advantage of multi-user cooperative spatial diversity and the time diversity and coding gain from retransmission mechanism.
