Abstract
The present invention provides a method and system for synchronizing a receiver. The method includes receiving a plurality of wireless signals that have traveled through at least one of multiple transmitter antennas and multiple receiver antennas. The receiver is time and frequency synchronized to each of the wireless signals based upon joint statistics of the plurality of wireless signals. The joint statistics can be a function of data patterns, time of arrival estimations, frequency offset estimations, phase offset estimations, timing offset estimations, error correction codes, post processing SNR, pre-processing SNR, PER, BER, correlator outputs, delay spread or doppler spread, of each of the plurality of wireless signals.

15. A synchronized receiver, comprising:
-
a frequency down converter for frequency down converting a plurality of received signals;
an ADC for digitizing the frequency down converted received signals;
a data stream segmenter receiving the digitizing the frequency down converted received signals and generating data stream segments;
a data processing unit receiving the data stream segments and generating a data out stream, and data statistics for each of the received signals;
a time/frequency controller receiving the data statistics, the time/frequency controller generating time a frequency controls of the frequency down-converter, the ADC and the data stream segmenter based upon joint summations of the data statistics. - View Dependent Claims (16, 17, 18, 19, 20)
