WIRELESS COMMUNICATION THROUGHPUT ENHANCEMENT BASED ON DELAYED CHANNEL GAIN INFORMATION

摘要

Channel gain information is utilized for determining linear, or non-linear, combinations of transmitted symbols to increase symbol throughput. The base station recombines symbols directed to different receivers in response to the channel gain information. Channel gain information, which is subject to delay, has been previously utilized merely for predicting current channel gains prior at the time of transmission. The present invention, however, utilizes the channel gain information to increase coding efficiency even when the channel gain information is not utilized for predicting current channel gains. The method, appparatus and systems of the invention are applicable to any configuration of multiple wireless transmission to multiple receivers.
