Abstract

本发明提供了一种多输入多输出通信系统的时间延迟估计方法，包括：接收机计算MIMO多输入多输出通信系统的信道响应矩阵，其中，该MIMO通信系统中有n个发射通道和m个接收通道，n≥2，m≥2，信道响应矩阵包含n*m个子信道的信道响应；接收机根据信道响应矩阵计算n*m个子信道分别相对于参考子信道的整数时间延迟，其中，参考子信道为n*m个子信道中任意一个子信道；接收机根据信道响应矩阵计算n*m个子信道的分数时间延迟；接收机根据n*m个子信道的时间延迟分离出m个接收通道的时间延迟。本发明还提供了一种估计装置和系统，可以实时在线地对MIMO通信系统各通道的整数时间延迟和分数时间延迟进行估计，测量精度高。
