Patent ID: 7643541

Claim:
A device for determining a correlation value from a correlation between a first sequence of values with complex values and a second sequence of values with complex values, wherein the first sequence of values is part of a receive sequence, and wherein the second sequence of values is a transmit sequence, and wherein the transmit sequence stems from a transmitter, the device comprising: a correlator configured to determine a first partial correlation value from a correlation between a first subset of the first sequence of values and a first subset of the second sequence of values, and a second partial correlation value from a correlation between a second subset of the first sequence of values and a second subset of the second sequence of values; a processor configured to determine a processed partial correlation value with an adjusted phase term from the first partial correlation value or the second partial correlation value; and a calculator configured to determine the correlation value using the processed partial correlation value, wherein the partial correlation values have different phase terms in a complex plane, and wherein the processor is configured to determine the adjusted phase term of the processed partial correlation value in dependence on the phase terms of the partial correlation values.
