本文研究了基于增量冗余（IR）的混合自动请求协议的重传分集多址接入（RTxD）。为了减轻多址干扰，我们采用连续的干扰消除在接收机和推导出的条件，所有的信号从活跃的用户可以成功地解码在一定数量的重传的IR块。我们考虑两种特殊情况下，我们来自两个多信道随机接入方案，在功率和速率域的子信道。通过分析和仿真，我们可以表明，所提出的RTxD随机接入方案可以优于其他现有的类似RTxD随机接入方案。
We consider multiple access with re-transmission diversity (RTxD) based on a hybrid automatic request protocol with incremental redundancy (IR) in this paper. In order to mitigate multiple access interference, we employ successive interference cancellation at a receiver and derive conditions that all the signals from active users can be successfully decoded within a certain number of re-transmissions of IR blocks. We consider two special cases, which we derive from two multichannel random access schemes that have sub-channels in the power and rate domains. Through the analysis and simulations, we can show that the proposed RTxD random access schemes can outperform other existing similar RTxD random access schemes.
