METHOD AND RECEIVER FOR ESTIMATING THE CHANNEL IMPULSE RESPONSE USING A CONSTANT MODULUS INTERFERENCE REMOVAL ITERATION

摘要

A receiver and associated method estimates a channel impulse response of the communications signal. A communications signal is received as a burst of transmitted symbols, including a known training sequence. The joint estimation of timing offset and initial channel impulse response is determined based on the cross-correlations of the known transmitted symbols and received communications signal. A constant modulus interference removal iteration is applied to improve the initial channel impulse estimation.
