摘要
在采用LMS算法实现回波抵消功能的同频数字直放站中,针对节省资源来降低成本的问题,结合Pipeline和Systolic技术,提出了复数DLMS算法的2倍复用结构。由测试结果可知,所提的结构在节省了一半乘法器资源的基础上实现了回波抵消功能。
To save resources and reduce cost for single frequency repeater,which uses LMS algorithm to cancel echo,two-replicated architecture of complex DLMS algorithm is presented,which combines pipeline and systolic technology. According to simulation results,the proposed architecture achieves echo cancellation under the condition of saving a half of multiplier resources.
