增强型网格编码多址(ETCMA)

Enhanced Trellis Coded Multiple Access (ETCMA)

Alberto G. Perotti, Branislav M. Popovic

摘要:

我们提出了一个增强版本的网格编码多址接入(TCMA),一个过载的多址接入方案,优于原来的TCMA在实现的频谱效率。增强型TCMA(ETCMA)执行旨在用于经历相似信噪比的用户的多个数据流的同时传输,并且可以在无线系统的上行链路和下行链路中采用,从而克服了TCMA的主要限制之一。得益于新的接收器算法,ETCMA能够提供显著更高的频谱效率。我们表明,ETCMA方法的能力的加性高斯白噪声信道的信号噪声比的范围很广。

英文摘要:

We propose an enhanced version of trellis coded multiple access (TCMA), an overloaded multiple access scheme that outperforms the original TCMA in terms of achieved spectral efficiency. Enhanced TCMA (ETCMA) performs simultaneous transmission of multiple data streams intended for users experiencing similar signal-to-noise ratios and can be employed both in the uplink and in the downlink of wireless systems, thus overcoming one of the main limitations of TCMA. Thanks to a new receiver algorithm, ETCMA is capable of delivering a significantly higher spectral efficiency. We show that ETCMA approaches the capacity of the Additive White Gaussian Noise channel for a wide range of signal-to-noise ratios.
