Abstract
An orthogonal frequency-division multiplexed (OFDM)-based receiver for channel tracking with signal-to-noise ratio dependent parameters that includes a memory; and a signal processor, coupled to the memory. The signal processor to estimate a signal-to-noise ratio (SNR) for a received packet of OFDM symbols and determine an SNR region in which the SNR estimate falls, wherein the signal processor implements a different set of finite impulse response (FIR) filter coefficients for each SNR region.
