Channel estimation using linearly constrained filter coefficients

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 each having a magnitude; generating ( 220 ) a set of raw channel estimates based on the set of demodulator output samples and the corresponding set of reference symbols; determining ( 230 ) a set of linearly-constrained filter coefficient parameters; and combining ( 240 ) the set of raw channel estimates with the set of linearly-constrained filter coefficient parameters to generate a channel estimate.
