    Abstract: A programmable correlator for a communication system includes an input queue coupled with an analog-to-digital converter (ADC). The input queue includes a random access memory (RAM) wherein sampled data streams from the ADC are written into the RAM. The input queue has two banks of memory of width 2M. A flexible complex correlator is operable on M samples. The correlator is coupled to read M complex samples out of 2M samples from the input queue. A pseudo-noise (PN) crossbar unit operates to rotate a generated PN code to match a rotation of the input queue data in the complex correlator.
