<P>PROBLEM TO BE SOLVED: To provide a method and apparatus to compute the combiner coefficients for wireless communication systems for a space-time solution. <P>SOLUTION: One embodiment trains the weights on a signal known a priori that is time multiplexed with other signals, such as a pilot signal in a High Data Rate, HDR, system, where the signal is transmitted at full power. A Minimizing Mean Square Error, MMSE, approach is applied allowing weight combining on a per path basis. The weights are calculated as a function of a noise correlation matrix and spatial signature per path. The noise correlation matrix is determined from an autocorrelation matrix of the received signal. The MMSE approach is applied to a non-time gated pilot signal. <P>COPYRIGHT: (C)2013,JPO&INPIT |
