摘要翻译：
利用统计力学的方法，研究了LDPC编码下无时延中继信道的典型特性及其多个单元的推广，即中继阵列。在所研究的系统中，在Nishimori温度下，利用精确的复制对称ansatz解析地解决了一种解调前向策略。特别地，通过中继消息在通信性能上的改进的典型水平在中继单元数量少和数量多的情况下表现出来。

英文摘要：
  The typical behaviour of the relay-without-delay channel and its many-units generalisation, termed the relay array, under LDPC coding, is studied using methods of statistical mechanics. A demodulate-and-forward strategy is analytically solved using the replica symmetric ansatz which is exact in the studied system at the Nishimori's temperature. In particular, the typical level of improvement in communication performance by relaying messages is shown in the case of small and large number of relay units.
