摘要：

Channels with a sparse impulse response arise in a number of communication applications. Exploiting the sparsity of the channel, we show how an estimate of the channel may be obtained using a matching pursuit (NW) algorithm. This estimate is compared to thresholded variants of the least squares (LS) channel estimate. Among these sparse channel estimates, the NIP estimate is computationally much simpler to implement and a shorter training sequence Is required to form an accurate channel estimate leading Q) to greater information throughput.
