Abstract

The algorithm and implementation of the differential direct sequence spread spectrum multi-sign detector was studied in this paper.The differential direct sequence spread spectrum multi-sign detector algorithm was derived from the differential multi-sign detecting algorithm.The Barker code differential direct sequence spread spectrum multi-sign detector with the gain of 13 and the simultaneously detecting number of

=4 has been implemented by using the fusion design structure of SAW matching filter and fixed delay line.The de-spread spectrum and demodulation performances of the detector have been tested and analyzed as well.
