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. |
