同频同时全双工数字自干扰抵消算法
Digital cancellation algorithms of in-band full duplex
摘要
Abstract
In-band full duplex is a key concept brought up in 5G,of which the key technology is self-interference (SI)cancel-lation.Since digital cancellation is simpler,more flexible and more efficient among all the cancellation techniques,it has attrac-ted much attention and become a promising way to reduce the cost,power consume as well as complexity.This paper firstly in-troduced the principle of the basic digital cancellation algorithm,namely,channel estimation and self-interference reconstruc-tion.And then it gave some recent researches on modified algorithms for either developing the adaptability and the accuracy of reconstructed SI or implementation simplification.Finally,it provided an outlook of the future work as a possible reference for the full duplex architectures and cancellation algorithms design.关键词
