TR UWB通信系统中基于信道特征序列的数字加权自相关接收机

Weighted autocorrelation receivers have been proposed in the literature to suppress noise or interference for transmitted reference ultra-wideband communication systems. Usually weight optimization is performed for partitioned integration bins. To improve the optimization effect, this paper proposes a digital weighted autocorrelation receiver, in which the sampled auto-correlated signal is first rearranged following a channel characteristic vector that sorts the strengths of the received channel
