Title:
METHOD AND APPARATUS FOR PERFORMING MODULATION/DEMODULATION IN A WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO2005032159
Kind Code:
A3
Abstract:
A method and apparatus for processing a data symbol is described. In one embodiment, the data symbol is modulated to produce a modulated data symbol. The modulated data symbol is encoded to generate an embedded offset in the modulated data symbol. The modulated data symbol is then transmitted with the embedded offset. In another embodiment, a modulated signal having an embedded offset is received. A symbol estimate is derived from the modulated signal. The symbol estimate is then applied to demodulate the modulated signal.
