Abstract
Embodiments of the present invention include techniques for performing cross correlations. In one embodiment the present invention includes a cross correlation system for use in a communication system comprising a wireless receiver receiving a signal including a first sequence of data values and converting the first sequence of data values into a sequence of digital data values, the wireless receiver further comprising a plurality of cross correlators that each receive the digital data values and cross correlate the digital data values with a corresponding plurality of different binary reference patterns, wherein if the first sequence of data values correlates with one of said plurality of binary reference patterns, one of said cross correlators generates a peak. In one embodiment, the cross correlators are partitioned into stages. In another embodiment, the received data values are loaded into a memory that is shared by the cross correlators to reduce hardware requirements.
