Abstract
A radio communication device (100) for recovering information from a received signal includes a demodulator (110) for demodulating the received signal into in-phase (I) and quadrature (Q) components and a multiplier (115) for multiplying the I and Q components together to generate a multiplied waveform. A polarity detector (125) coupled to the multiplier (115) determines from the multiplied waveform a polarity variable indicative of a data symbol, and a processor (135) recovers the information from the received signal in accordance with the data symbol.
