Abstract
A wireless receiver including a baseband processor that includes a compensation system that selectively includes an equalizer and a CMF that process received digital samples from a wireless medium, and a CIR estimator that calculates filter weights based on the samples. A memory stores default filter weights and select logic selects between calculated filter weights of the CIR estimator and the default filter weights from the memory. An SNR estimator receives the samples and provides an SNR metric and a multipath estimator receives the calculated filter weights and provides a multipath metric. The decision logic determines an operating point of the receiver using the SNR and multipath metrics, makes a decision based on the determined operating point according to a predetermined packet error rate (PER) performance mapping, and controls the select logic to select between the default and calculated filter weights and selectively enables the equalizer.
