Patent ID: 8345781

Claim:
A method comprising: generating an initial set of bit capacity values, including: for each subcarrier capacity value of a set of subcarrier capacity values, expanding the subcarrier capacity value based on a modulation order, the expanding to generate multiple respective ones of the set of bit capacity values, wherein an order of the initial set of bit capacity values is according to the frequencies of the set of subcarrier capacity values; deinterleaving the initial set of bit capacity values to determine an ordered set of bit capacity values for subcarriers of an orthogonal frequency division multiplexed (OFDM) communication channel; selecting a sample size to determine a moving average of the ordered set of bit capacity values; determining an ordered set of average bit capacity values representing a moving average of the ordered set of bit capacity values based on the selected sample size; and identifying a channel quality indicator (CQI) of the OFDM communication channel, the identifying including selecting a minimal value from the ordered set of average bit capacity values.
