ABSTRACT:
Known chip equalizers for Wideband-Code Division Multiple Access (W-CDMA) employ a co-efficient calculator that implements a Minimum Mean Square Error (MMSE) solution to a least squares technique for obtaining equalizer coefficients in response to receipt of a pilot sequence. However, this solution results in an undesirably high processing overhead in downlink receivers operating in a W-CDMA communications system. Consequently, the present invention provides a computationally simpler technique to calculate equalizer coefficients by implementing a minimum-norm solution to the least squares problem.
