摘要
Provided is an alternative physical interpretation of the wireless channel impulse response using the knowledge of the antenna impulse responses. As a result, it can be shown that the clusters in the popular Saleh-Valenzuela model actually represent one multipath component only, not several rays as is often assumed. This knowledge has a significant impact on receiver architecture since the number of fingers in a rake receiver can be reduced significantly, for some systems by a factor of up to eight. The drawback of the method is an increase in processing complexity in each finger, but it is anticipated that the overall processing complexity in the receiver will be reduced.
