Abstract
A method of and data processing system for determining whether a received signal in a Code Division Multiple Access system that uses an antenna array includes a desired signal with a predetermined timing offset, the method including correlatingthe received signal with a spreading code having the predetermined timing offset and corresponding to the desired signal at each element of the antenna array to provide correlations; determininga power distribution, such as a DFT, corresponding to the correlations that is a function of a direction of arrival of the received signal; comparinga magnitude of the power distribution at a first direction of arrival to a threshold that has a value that varies with the direction of arrival; and when the threshold is satisfied, determiningor indicating that the desired signal is likely present at the first direction of arrival.
