摘要

考虑了在矢量析取信道上，当用户传输长度为l的矢量时，一类特殊的多址系统的信码结构，该方案基于Gilbert-Varshamov界上的码，可以估计码率的可达极限。为了分析相对和率的复杂表达式，我们给出了一个估计。给出了相对和速率的最优参数的仿真结果。仿真结果表明，最大可达和速率约为0.35。

Signal-Code Construction Based on Codes on Gilbert-Varshamov Bound for Multiple Access System over Vector-Disjunctive Channel

We consider a signal-code construction for a special class of multiple access system over vector-disjunctive channel when users transmit some vector of bits of length L. Suggested scheme is based on codes on Gilbert-Varshamov bound that allows us to estimate reachable limit of code rate. In order to analyze complex expression of relative sum-rate we provide an estimation. We present simulation results for optimal parameters for relative sum-rate. Simulation results we obtained allow us to conclude that maximum achievable sum-rate is about 0.35.
