Abstract
A method of multi-symbol channel estimation for estimating channel response to a plurality of transmission symbols within an observation window transmitted through a time-varying channel in a multi-carrier modulation system is provided. The method is to be implemented using a channel estimation device, and includes the steps of: obtaining a window pilot receive vector according to a part of elements of each of receive symbols corresponding to pilots in a corresponding one of the transmission symbols; computing a window pilot channel trans form matrix based upon the pilots in the transmission symbols; computing an estimated value of a polynomial coefficient vector based upon the window pilot receive vector and the window pilot channel transform matrix; and for each of the transmission symbols, computing a plurality of estimated values of channel response associated with possible transmission paths in the time-varying channel according to the estimated value of the polynomial coefficient vector.
