Patent ID: 7346114

Claim:
A receiver comprising: an A/D converter for converting receiver analog signals to a digital signal data stream, wherein the digital signal data stream includes symbols separated by guard segments; an I/Q demodulator for producing a first set of I and Q components; a first carrier signal offset estimator and a first symbol synchronizing signal generator, each using the first set of I and Q components, to estimate the offset of the carrier signal and provide a signal for adjusting the A/D converter and to generate a symbol synchronizing signal for the extractor, respectively, at least during an initialization phase of the receiver; a guard segment length detector using the first set of I and Q components; an extractor for identifying and removing the guard segments of the detected length from the digital signal data stream; and an FFT demodulator for demodulating the symbols of the digital signal data stream to produce second sets of complex I and Q components.
