摘要
A method for processing spread spectrum signals through a two step integration process in a circuit having an intermediate frequency signal preprocessing unit and a plurality of block integrators, wherein the circuit receiving a digitized signal, a local reference signal, and a pseudorandom noise code. The method includes generating a plurality of data streams by the intermediate frequency signal preprocessing unit using the digitized signal and the reference signal, receiving at each block integrator a data stream from the plurality of data streams and the pseudorandom noise code, performing a predetermined number of partial correlations at each block integrator using hybrid correlation technique based on the data stream and the pseudorandom noise code to obtain a predetermined number of partial correlation results, and computing a predetermined number of complete correlation results based on the predetermined number of partial correlation results. Each data stream is generated every predetermined time period.
