Method and protocol to adapt each unique connection in a multi-node network to a maximum data rate

摘要

A rate-adaptive mechanism for optimizing transmitter/receiver connections on a carrier-by-carrier basis for maximum date rate based on channel attributes for that connection and direction. Channel information is produced by a channel adaptation process based on channel characteristics 506 and is stored in both a transmitter 12a and receiver 12b as a channel map in transmitter (TX) channel maps 346 with an associated channel map index 142 for channel map look-up. The channel map index 142 for a channel map used to modulate a payload 82 of a frame 80 is conveyed by the transmitter 12a to the receiver 12b in the frame 80 so that the receiver 12b is able to select the correct channel map for demodulation. <IMAGE>
