摘要
A multiple carrier wireless communications system includes a channel predictor, a performance predictor, and a link adapter. The channel predictor is configured to predict channel state information for a next packet based on channel state information for the current packet. The performance predictor includes an uncoded performance predictor configured to predict system performance at an input of a decoder based on a modulation type and the predicted channel state information for the next packet, and a decoder input-output performance mapper configured to determine a required coding rate based on a requested system performance and the predicted system performance at the input of the decoder. The link adapter includes a modulation and coding scheme (MCS) updater configured to identify a MCS based on the required coding rate.
