Abstract
Channel estimator circuitry and associated method for a digital receiver operates to estimate a channel impulse response of a transmission channel. When intersymbol interference is introduced upon a communication signal only by circuitry of a transmitter and a receiver, the quality of channel estimation is improved. Even when intersymbol interference is introduced upon a communication signal during its transmission, the quality of channel estimation is improved by decomposing the components of the intersymbol interference into portions introduced during transmission of the signal upon a communication channel and portions introduced by the transmitter and receiver circuitry.
