ABSTRACT:
An apparatus comprises a link interface to receive an OFDM symbol from a communications link. A signal-to-noise ratio estimation unit generates an estimate of a geometric signal-to-noise ratio for the received symbol based on a function of the soft and hard decisions. A signal quality of the wireless communications link is based on the geometric signal-to-noise ratio.
