Patent ID: 7751493

Claim:
A signaling method over multiple channels in a wireless telecommunication systems including a transmitter and receiver, comprising: obtaining an information bit stream; selecting number of transmission streams; selecting different transmission rates based on diversity order of each eigen-mode for each MIMO (multiple-input-multiple-output) OFDM (orthogonal frequency division multiplexing) transmission; performing back-off for a SNR (signal to noise ratio) requirement corresponding to the diversity order, wherein back-off decreases as the diversity order of each eigen-mode increases; computing a back-off table based on diversity order as: Diversity Back-off Order (dB) 1 12 2 7 3 3 4 2 5 and up 1; and transmitting the information bit stream for the transmitter via said multiple channels over a plurality of transmitter antennas to the receiver according to the selected transmission rate per channel.
