Summary:Blind identification of FIR multichannel using higher-order statistics (HOS) is investigated. A new linear approach is proposed which generalizes the weighted slices method for single FIR channel estimation. By finding the proper linear combinations, channel response is obtained from the weighted cumulant matrix with Toeplitz structure. This general algorithm works for both single user and multiuser scenario. It relaxes the identification condition of the original method and demonstrates performance improvement
