Abstract:
1. An apparatus for processing a composite wireless communication signal including a plurality of multi-path components, comprising: an input for receiving the composite wireless communication signal from an antenna; an extraction portion coupled to said input for extracting from the composite wireless communication signal a plurality of signals that respectively correspond to said multi-path components, said extracting portion includes a plurality of delay elements coupled to said input for applying a plurality of delays to said composite wireless communication signal; a space-time decoder portion coupled to said extraction portion for applying space-time decoding to said plurality of signals to produce a corresponding plurality of space-time decoded signals; a decision portion coupled to said space-time decoding portion for deciding communication symbols in response to said space-time decoded signals; a space-time encoding portion coupled to said decision portion for applying space-time encoding to the decided communication symbols to produce a space-time encoded signal; a multi-path portion coupled to said space-time encoding portion for applying a multi-path effect to said space-time encoded signal to produce a plurality of space-time encoded multi-path signals which respectively correspond to said multi-path components; and a combiner coupled to said multi-path portion and said input for combining said space-time encoded multi-path signals with said composite wireless communication signal to cancel interference from said multi-path components of said composite wireless communication signal.
