Patent ID: 7564917

Claim:
A multicarrier receiver comprising: Fourier transform circuitry to generate frequency-domain signals from consecutively received multicarrier symbols concurrently transmitted by at least two transmit antennas; a channel estimator to generate channel estimates from training components of the frequency-domain signals of the consecutively received multicarrier symbols; a common phase error (CPE) estimator to generate CPE estimates by using the channel estimates provided by the channel estimator and by using the training components of the frequency-domain signals of the consecutively received multicarrier symbols provided by the Fourier transform circuitry; and a space-time decoder to decode data components of the frequency-domain signals of the consecutively received multicarrier symbols by using both the channel estimates and the CPE estimates, wherein the CPE estimator generates a first CPE estimate for a first channel between the receiver and a transmitter and generates a second CPE estimate for a second channel between the receiver and the transmitter, wherein the CPE estimates are generated to compensate for uncoupled phase noise resulting from the transmission of the multicarrier symbols with an independent local oscillator associated with each of the transmit antennas, and wherein the consecutively received OFDM symbols comprise first and second consecutively received OFDM symbols that are consecutively transmitted by the transmitter and include first and second interleaved pilot sequences.
