Abstract
A method, apparatus and system are disclosed herein for channel classification and adaptation. In one embodiment, the system comprises a base station having a transmitter that is operable to transmit wireless signals using a plurality of transmission options; and a user terminal having a receiver that is operable to receive and decode wireless signals using a plurality of receiver algorithms, where the user terminal is operable to receive communications from the transmitter over a multiple-input, multiple output (MIMO) channel, to select at least one coding mode to be used by the transmitter on the channel based on rates achievable using MIMO transmission, in view of the channel information, using different combinations of one of the plurality of receiver algorithms and one of the plurality of transmission options, and to send information to identify the at least one coding mode to the base station using a feedback channel, each coding mode specifying at least an encoder to be used by the transmitter for the channel.
