Patent ID: 7599443

Claim:
A method to operate a wireless multiple input/multiple output MIMO communication system, comprising: for N symbols of a frame of information to be transmitted through a plurality of eigen sub-channels, allocating N 1 symbols to a stronger eigen sub-channel and N 2 symbols to a weaker eigen sub-channel, where N 1 >N 2 , and wherein N, N 1 and N 2 indicate, respectively, numbers of symbols; determining a probability of reception error when transmitting the N 2 symbols through the weaker eigen sub-channel for an auxiliary signal-to-noise ratio; solving for a quality of service QoS of the weaker eigen sub-channel; and if the QoS is less than a desired QoS, decreasing the value of N and repeating allocating symbols, determining the probability of reception error and solving for the QoS.
