Abstract:
1. A method of detecting a data symbol sequence transmitted over a wireless communications channel, the method comprising: receiving, by a detector in a receiver, a plurality of data symbol sequence copies, each data symbol sequence copy comprising: generating, by the detector, an initial phase vector for each data signal in the plurality of data signal sequence copies, each initial phase vector is based on the plurality of data signal sequence copies; generating, by the detector, an estimated symbol detection for each data signal in each of the plurality of data symbol sequence copies, each estimated symbol detection sequence is based on a corresponding initial phase vector; generating, by the detector, a quality value for each estimated symbol detection sequence; selecting, by the detector, a global estimated phase vector, the global estimated phase vector is the estimated phase vector for the estimated symbol detection sequence having a quality value that is the highest of all quality values; and detecting, by the detector, the data symbol sequence by: b) combining each of the phase shifted plurality of data signal sequence copies to obtain the data symbol sequence.
