Patent ID: 7272190

Claim:
A method for performing adaptive modulation and coding of a data stream in a multi-carrier communication system employing a plurality of subcarriers, wherein the plurality of subcarriers are divided into bins of subcarriers, the method comprising the steps of: receiving a channel-quality report comprising a value related to a mean in channel quality for at least one bin of subcarriers; determining an expected FER AWGN (γ eff ) for a set of modulation and coding scheme candidates based on the channel-quality report, where γ eff is an effective signal-to-noise ration (SNR) that would yield a same frame error rate (FER) in an adaptive White Gaussian noise (AWGN) channel; determining a modulation and coding scheme for the data stream based on the expected FER AWGN (γ eff ); and utilizing the modulation and coding scheme to transmit the data stream over the multi-carrier communication system.
