Patent ID: 8184724

Claim:
A wireless communication system, comprising: at least one sending-side wireless transceiver configured to transmit a feedback request, and at least one receiving-side wireless transceiver configured to receive the feedback request and generate a channel state information to the at least one sending-side transceiver on a feedback loop, wherein the at least one sending-side wireless transceiver has a function of deriving transmit weight vectors including optimum power allocation for a channel based on the channel state information from the at least one receiving-side wireless transceiver, carrying out the feedback request by using the transmit weight vectors, and estimating a difference between the channel at the time when the transmit weight vectors are derived and an actual channel, and as the difference between the channel at the time when the transmit weight vectors are derived and the actual channel increases, the power allocation is caused to approach asymptotically to equal allocation from a value at the time when the transmit weight vectors are derived.
