Abstract
A method for multi-user detection in a CDMA communication system using a finite-impulse-response matrix filter includes a first step of inputting a received sequence of multi-user data from a channel of the communication system. A next step includes truncating a block convolution matrix representing an infinite-impulse-response matrix filter so as to provide a finite-impulse-response matrix filter equalizer by using a system matrix with smaller number of columns than the frame length. A next step includes operating on the received sequence of multi-user data with the finite-impulse-response filter so as to provide an estimate of user data for any particular user.
