The Fgpa The Baseband Spread-spectrum Signal Processor-based Design And Realization

In this paper,the overall design scheme of a kind of DS/SSMA signal processoris developed according to the FPGA technology.With this processor,We can processthe baseband signals in DS/SSMA communication system.There is importanttheoretical and practical significance in developing Intellectual Property(IP)on our own basis of spread spectrum signal processing methods.The theory and application of EDA and FPGA are introduced in this paper,and are described as well the principle theory and current development in spread-spectrum communication technology.Then the design of DS/SSMA baseband signalprocessor based on FPGA is discussed,it is made up of two models-—the transmitterand the receiver.The models of it are implement detailedly using Altera's FLEX10KFPGA.At last,the software simulation is carried out with QuatusⅡ software andsome models are programmed to FPGA.The results of simulation proved the validityof scheme design.
