Patent ID: 7912118

Claim:
In a wireless receiver for receiving a signal via a communication channel subjected to multi-path interference, the wireless receiver comprising an RF receiving unit, an analog to digital converter, and digital processing hardware, said signal transmitted without a cyclic prefix using a single carrier frequency, a method of channel equalizing comprising: a) receiving the transmitted signal with the RF receiving unit, and converting thereof into a sequence of samples of the transmitted signal using the analog to digital converter, each sample representing a transmitted symbol subjected to channel distortions; b) based on an initial channel estimation, generating, with the digital processing hardware, a frequency response transfer function (h f ) for a block of transmitted symbols of a pre-defined length, and a time-domain channel echo response function (C T ); c) using the digital processing hardware for iteratively equalizing blocks of samples from the received sequence of samples using a frequency-domain equalization in a feedforward path, and time-domain inter-block echo cancellation and cyclic echo correction in a feedback path.
