本文研究了两用户多址接入信道（MAC）中的编码分集增益。我们提出了一个简单的分布式空时频分组编码（D-STFBC）方案，并分析了所提供的分集增益。特别是，我们表明，充分的多样性（3阶）是可能的，如果合作是足够好的，严格的信号处理，假设在发射机和接收机。误码率（BER）的分析和曲线提供说明的目的。
In this paper, we investigate diversity gain in coding for a 2-user multiple-access-channel (MAC) with cooperating transmitters-the MAC with relaying. We propose a simple distributed space-time-frequency block coding (D-STFBC) scheme and analyze the offered diversity gain. In particular, we show that full diversity (order 3) is possible if collaboration is well enough and rigorous signal processing is assumed both at the transmitters and the receiver. Bit-error-rate (BER) analysis and curves are provided for illustrative purposes.
