ITERATIVE CALCULATION OF COEFFICIENTS FOR A MULTICARRIER EQUALISER

摘要

An multicarrier adaptive channel equalizer is provided, which has a coefficient adaptation branch that updates the filter coefficients based upon a weighted average of previous coefficient values and decisions for the current symbol. An override or nulling of the weighting factor is provided to mitigate the effects of noise on the current symbol. An embodiment of the OFDM adaptive channel equalizer requires only one coefficient memory port, and only two multipliers as in a non-adaptive equalizer thereby allowing a cost effective hardware implementation.
