Abstract
A transceiver includes a receiver configured to receive a radio frequency (RF) signal via a wireless communication link. The wireless link has a predetermined link characteristic. The RF signal includes a plurality of encoded Orthogonal Frequency Division Modulation (OFDM) symbols. A receive baseband processor recovers each OFDM symbol encoded within the RF signal. The baseband processor includes an estimation unit configured to continuously measure a signal quality of the wireless communication link based on each recovered OFDM symbol. A MAC layer controller is configured to selectively alter the predetermined link characteristic of the wireless link on an ongoing basis based on the continuously measured signal quality of the wireless communication link.
