HYBRID DOMAIN BLOCK EQUALIZER

摘要

The invention provides a method and device for iterative hybrid time-frequency domain block equalization of signals received via a communication channel subject to multi-path interference. The equalization method includes frequency-domain equalization of blocks of received signals in a forward path, and time-domain inter-block echo correction and intra-block cyclic echo addition in the feedback path. The invention can be used for equalizing signals transmitted without cyclic prefix and subjected to multi-path interference with long delay spread.
