System and method for detecting direct sequence spread spectrum signals using pipelined vector processing

摘要

System and method for using pipelined vector processing in the detection of direct sequence spread spectrum signals. A preferred embodiment comprises a memory (such as memory 507) used to store a plurality of hypotheses, a PN sequence generator (such as PN generator 527) that can generate PN sequences for each of the hypotheses, and vector processing correlators and accumulators (both coherent and non-coherent). The PN sequence generator can arbitrarily generate PN sequences for any hypothesis, permitting the simultaneous testing of multiple hypotheses. A searcher controller (such as search control unit 319) can schedule access to different units in a pipelined fashion to increase the number of hypotheses tested in a given period of time.
