Patent ID: 7058144

Claim:
A wireless receiver, comprising: a radio that converts radio frequency (RF) signals received from a wireless channel to baseband signals; and a baseband processor, coupled to the radio, comprising: an analog to digital converter (ADC), coupled to the radio, that samples the baseband signals at a predetermined sample rate and that provides corresponding digital samples; a compensation system, coupled to the ADC, that selectively provides compensation to the digital samples; a channel impulse response (CIR) estimator, coupled to the ADC, that calculates filter weights based on the digital samples; a signal to noise (SNR) estimator, coupled to the ADC, that receives the digital samples and that provides an SNR metric; a multipath estimator, coupled to the CIR estimator, that receives the calculated filter weights and that provides a multipath metric; and decision logic, coupled to the SNR and multipath estimators and the compensation system, that determines an operating point of the receiver based on the SNR and multipath metrics and that controls the compensation system according to the predetermined packet error rate (PER) performance mapping.
