同时同频全双工射频快速自适应干扰抵消算法
Quick Adaptive Self-Interference Cancellation at RF Domain in Full Duplex Systems
摘要
Abstract
In a full-duplex transceiver which transmits and receives at the same frequency simultaneously, a radiofrequency (RF) adaptive self-interference cancellation algorithm based on quick search is proposed to cancel the single path self-interference. By analyzing the impact of the magnitude and phase estimation errors on the residual received signal power after the self-interference cancellation, the RF quick adaptive self-interference cancellation algorithm is derived, and its convergence performance is discussed. By analysis and simulation, the RF adaptive self-interference cancellation algorithm based on quick search can effectively cancel the self-interference at the RF domain, and its convergence time decreases by 60% compared with the existing RF adaptive self-interference canceller.关键词
