Method and apparatus for reference symbol aided channel estimation

摘要

A system that includes a receiver ( 100 ) that is configured for: selecting ( 210 ) a set of demodulator output samples and a corresponding set of reference symbols; generating ( 220 ) a set of raw channel estimates based on the set of demodulator output samples and the corresponding set of reference symbols; subdividing ( 230 ) the set of raw channel estimates into a plurality of subsets; assigning and applying ( 240 ) a corresponding reference symbol magnitude quantization scheme to each subset; determining ( 250 ) a set of filter coefficients that is based on the quantization schemes applied to the subsets of raw channel estimates; and combining ( 260 ) the set of raw channel estimates with the set of filter coefficients to generate a channel estimate.
