Abstract
For multichannel multiuser detection in a wireless communication system such as a CDMA system, for a set of user spreading codes, coefficients to delay lines are adjusted and the delay line output processed to estimate a symbol. The symbol is estimated based on a space-time correlation for an antenna space delay time correlation. The estimated symbol is then remodulated and subtracted from the received antenna signal corresponding to other users of the wireless communication system. The adjusting and processing are iterated until the estimated symbols converge such that they correspond to a predetermined symbol decision criteria.
