Patent ID: 8170160

Claim:
A method comprising: processing, using maximum ratio combining techniques, a first received symbol from each receive chain of a plurality of receive chains in a receiver, wherein a plurality of received symbols comprises the first received symbol; processing, using maximum ratio combining techniques, a second received symbol from each receive chain of the plurality of receive chains in a receiver, wherein the plurality of received symbols comprises the second received symbol, and wherein the first received symbol precedes the second received symbol; adding the processed first and the processed second received symbols from each receive chain of the plurality of receive chains in the receiver to generate a first sum; computing an angle of the first sum to generate a first phase offset estimate; acquiring a third received symbol and a fourth received symbol, wherein the plurality of received symbols comprises the third and the fourth received symbols and the first and the second received symbols precede the third and the fourth received symbols; processing, using maximum ratio combining techniques, the third and the fourth received symbols from each of the plurality of receive chains in the receiver; and applying, to the third and the fourth processed received symbols, the first phase offset estimate to generate a phase offset compensated third received symbol and a phase offset compensated fourth received symbol.
