FREQUENCY DOMAIN FEEDBACK CHANNEL ESTIMATION FOR AN INTERFERENCE CANCELLATION REPEATER INCLUDING SAMPLING OF NON CAUSAL TAPS

摘要

A method for estimating a feedback channel for a wireless repeater uses frequency domain channel estimation on samples of a pilot signal and samples of a receive signal. The pilot signal samples may be delayed to align the largest channel tap to a given reference time. A time domain feedback channel is generated by retaining both the causal taps and the non-causal taps of the channel estimate.
