Title: MITIGATION OF TRANSMISSION ERRORS IN MULTI ANTENNA SYSTEMS
Abstract:
Methods are disclosed for improving communications on feedback transmission channels, in which there is a possibility of bit errors. One method comprises the steps of choosing multiple mappings of indices to channel states, estimating the effect on transmission quality of feedback errors for each of the mappings of indices to channel states, selecting a mapping of indices to channel states to reduce the effect of feedback errors; and transmitting feedback of channel state information from the receiver to the transmitter, the receiver representing a channel state using the index determined by the selected mapping of indices to channel states.
