Title: Perturbation apparatus and method for user detection in a multiple-access communication system
Inventor: LU CHUN-CHIAN
IPC: H04B1/7105
Filed: 2001-11-23
Granted: 2003-06-11
Abstract: A single-user detection method operates to reduce the effects of interference in multi-user detection systems. Based upon a number of received user codes, a receiver defines a frame of symbols containing at least one window. A symbol amplitude of a single-user in a multi-user system is approximated over the window of the frame and a perturbative correction value is calculated based upon a correlation or decorrelation matrix, which is determined by the delay spread of the signals. An estimation of the symbol amplitude of the single-user signal is calculated over one or a number of windows of the frame. The single-user signal is detected when the symbol amplitudes of the entire signal within the frame has been calculated.
