Delay spread estimation for multipath fading channels

摘要

An efficient method of accurately estimating delay spread in multi-path transmission applications is based on quantifying the effect of the actual delay spread on the shape of the correlation energy profile between the received signal and the synchronization pattern of the receiver. Depending on the degree of the estimated delay spread, an appropriate demodulation technique is selected for optimizing the receiver performance over a range of channel multi-path conditions. The invention is applicable to digital wireless mobile communication systems, as well as to any device that performs characterization or testing of a transmission system.
