COMMUNICATION SYSTEM AND METHOD USING SUBSPACE INTERFERENCE CANCELLATION

摘要

A receiver performs interference mitigation under blind or semi-blind conditions using diversity present in the signal of interest or in the interferer. A first path interference mitigation procedure extracts training information from received signals, performs interference mitigation on the training information and estimates the channel. The second path interference mitigation procedure uses data extracted from the received signal and the channel estimate to perform interference mitigation. Each interference mitigation process can take the form of a lossy compression followed by decompression.

1. A method of communication in an OFDM system, the method comprising:
receiving a signal comprising at least one OFDM symbol; extracting training information from the OFDM symbol; performing interference mitigation on the extracted training information to produce reduced interference training information; performing channel estimation using the reduced interference training information to produce a channel estimate; and equalizing at least a portion of the OFDM symbol using the channel estimate.
