离散星座在高斯MAC信道上传输的可调速率

Achievable rates for transmission of discrete constellations over the Gaussian MAC channe

Rizwan Ghaffar, Dimitris Toumpakaris, Jungwon Lee

摘要:

在本文中,我们考虑的高斯多址接入信道(MAC)时,采用次优传输方案的可达速率区域。聚焦于两个用户的MAC和假设未编码的脉冲幅度调制(PAM),我们推导出一个速率区域,这是一个五边形,并提出了一种策略,它可以实现。我们还比较了该区域的外边界和正交传输。

英文摘要:

In this paper we consider the achievable rate region of the Gaussian Multiple Access Channel (MAC) when suboptimal transmission schemes are employed. Focusing on the two-user MAC and assuming uncoded Pulse Amplitude Modulation (PAM), we derive a rate region that is a pentagon, and propose a strategy with which it can be achieved. We also compare the region with outer bounds and with orthogonal transmission.
