Abstract:
1. A method for detection data in wireless communications transmitted in a code division multiple access (CDMA) communication system, the method comprising: (a) receiving the communications in a receiver; (b) converting the communications to a baseband signal; (c) sampling the base bandsignal to produce a received vector; (d) estimating channel responses of the received communications as a channel response matrix; (e) estimating a noise variance of the received communications; (f) scaling the noise variance by a scaling factor, said scaling factor being derived from at least one gain factor determined for at least one received communication; (g) equalizing the received communications using the channel response matrix and the scaled noise variance to produce a spread data vector; and (h) despreading the spread data vector to detect data of the received communications.
