Patent ID: 7787573

Claim:
A method for processing a diversity signal transmitted over a plurality of time-sensitive channel fading communication links, comprising: receiving a first data stream transmitted over a first time-sensitive communication link during a first time period (t 1 ) and a second data stream transmitted over a second time-sensitive communication link during a second time period (t 2 ), wherein the first and second data streams correspond to the transmit-diversity signal; multiplying said received first and second data streams by a mean square error [(H*·H+1/SNR) −1 ·H*], wherein H represents channel effects on the received first and second data streams and is represented by H = [ h 1 ⁡ ( t 1 ) h 2 ⁡ ( t 1 ) h 2 * ⁡ ( t 2 ) - h 1 * ⁡ ( t 2 ) ] , where h 1 (t 1 ) represents time-sensitive channel fading in the first communication link (h 1 ) during the first time period (t 1 ), h 2 (t 1 ) represents time-sensitive channel fading in the second communication link (h 2 ) during the first time period (t 1 ), h 2 *(t 2 ) is a complex conjugate of h 2 (t 2 ), which represents time-sensitive channel fading in the second communication link (h 2 ) during the second time period (t 2 ), and −h 1 *(t 2 ) is a negative complex conjugate of h 1 (t 2 ), which represents time-sensitive channel fading in the first communication link (h 1 ) during the second time period (t 2 ); and bypassing multiplication by the mean square error when substantially zero time-sensitive channel fading is present on the plurality of communication links.
