摘要
针对实际通信中存在的非线性回波问题,介绍了现有的非线性回波抑制解决方案,将各种纷杂的方案按照不同的模型分为三类,分析对比了不同类别解决方案的优劣,同时对不同解决方案之间进行了比较;最后指出现有解决方案的不足,展望了未来的非线性回波研究方向。
In view of the nonlinear echo problem in communication, the existing nonlinear echo suppression solutions are introduced. All kinds of scheme are separated into three types according to the different models. Then, comparison and short- age of different types is pointed out. Finally, future research direction of the nonlinear echo is forecasted.
