摘要

本文介绍了一种全双工无线系统中射频干扰消除技术的实现方法。详细分析了射频系统的缺陷，并给出了射频干扰消除的实现方法。测量结果表明，在静态环境下，考虑到1.9 GHz的干扰信号，带宽为5 MHz，对射频干扰的抑制超过50dB。在实际应用中，由于动态环境中的多重射频损伤，预计平均干扰抵消为35 dB。

Radio frequency interference cancellation in wireless communication systems

This article describes an implementation approach for the RF interference cancellation technique in full duplex wireless systems. A detailed analysis of the impairments in the RF system and the implementation of the RF interference cancellation are presented. Measurement results indicate more than 50dB suppression of the RF interference in static environments, considering a 1.9 GHz interference signal with 5 MHz bandwidth. In practice, due to multiple RF impairments in dynamic environments, an average interference cancellation of 35 dB is expected.
