摘要 回波(回声)抵消是数字直放站的一项关键技术,利用重发信号实现了基于自适应算法的回波信道估计以及回波抵消。仿真实验证明效果较好,并可满足数字直放站的实时性。 Echo canceller is the key technology for digital repeater. A performing method for channel estimation and echo cancellation based on adaptive algorithm is proposed. As the result of simulation, the echo could be cancelled and real-time quality of the digital repeater is more satisfied.
