摘要:

我们研究了多用户多路中继网络,其中$N$用户节点通过单个中继节点交换信息。我们在中继中使用网络编码来增加吞吐量。由于复杂度的限制,本文只考虑中继中的二进制多用户网络编码(BMNC)。我们研究了GF(2)中的BMNC矩阵,并提出了几种BMNC矩阵的设计准则,以提高误符号概率(SEP)性能。给出了系统SEP的封闭表达式。此外,SEP的上限也提出了进一步的见解系统性能。然后,BMNC矩阵的设计,以尽量减少错误概率。

英文摘要:

We study multi-user multi-way relay networks where $N$ user nodes exchange their information through a single relay node. We use network coding in the relay to increase the throughput. Due to the limitation of complexity, we only consider the binary multi-user network coding (BMNC) in the relay. We study BMNC matrix (in GF(2)) and propose several design criteria on the BMNC matrix to improve the symbol error probability (SEP) performance. Closed-form expressions of the SEP of the system are provided. Moreover, an upper bound of the SEP is also proposed to provide further insights on system performance. Then BMNC matrices are designed to minimize the error probabilities.
