METHOD FOR CHANNEL ESTIMATION AND DELAY SPREAD APPROXIMATION IN A WIRELESS COMMUNICATION SYSTEM

摘要

A method for delay spread approximation used in a wireless communication system comprises the steps of: retrieving a plurality of pilot symbols from a channel of a wireless communication system; calculating at least one parameter representing the shape of the frequency response of the channel according to the values and the relative positions of the pilot symbols; determining a representative parameter value according to the at least one parameter; and determining a delay spread value according to the representative parameter value.
