摘要

在本文中，我们考虑了一个全双工(FD)系统使用空间调制(SM)技术进行同步传输。尽管近年来对这两种技术的结合进行了研究，但器件的非线性效应一直被忽视。本文首次论证了非线性功率放大器(PA)对全双工空间调制(FDSM)系统的影响。采用数字消去器来处理PA非线性下的强自干扰。结果验证了所考虑的消除器可以抑制接近热噪声水平的SI，并且具有高可靠性，以确保系统的性能。

Nonlinear Power Amplifier Effects on a Full Duplex Spatial Modulation System

In this paper, we consider a full duplex (FD) system using spatial modulation (SM) technique for simultaneous transmission. Despite the recent studies on the combination of these two techniques, nonlinear effects of devices have been ignored. This paper demonstrates, for the first time, the nonlinear power amplifier (PA) effects on a full duplex spatial modulation (FDSM) system. A digital canceller is adopted to deal with the strong self-interference (SI) in presence of PA nonlinearities. The results are verifying that the considered canceller can suppress SI close to the thermal noise level and has high reliability to ensure the performance of the system.
