Abstract:
1. A receiving wireless transmit receive unit (WTRU) for processing concurrent communication signals from a plurality of transmitting WTRUs that concurrently transmit successive data blocks in a plurality of K forward channels, the receiving WTRU comprising: a receiver configured to receive successive data blocks of K concurrent transmissions transmitted from the transmitting WTRUs on the respective K forward channels; a processor configured to compute individual channel characteristics for each forward channel k based on the characteristics of data signals received on all K forward channel; and said processor configured to successively compute instantaneous Signal to Interference Ratio values for each forward channel j (iSIRj), for integers j=1 to K, based on a cross correlation matrix of channel response characteristics of K concurrently received data blocks and to selectively compute an average value that is used for the computing the individual channel characteristics for the forward channel k.
