The FPGA (field programmable gates array) as a large-scale programmable logic devices, the system structure and logic unit, flexible, integration, and wide application scope of short development cycle, design and manufacture of low cost, development tools and on-line inspection can be advanced, the product is widely applied in the prototype design and production. And the tradition of DSP (digital signal processor) or GPP (gm), FPGA processor in some signal processing tasks shows very strong performance, high throughput, architecture and algorithm, parallel computing and storage and distribution of the dynamic configuration advantages, therefore is very suitable for high-speed communication system design verification processing parts. Baseband The communications system based on FPGA baseband design verification platform using the large capacity and high performance FPGA device for communication system, the baseband design provides an effective realization of hardware platform. Based on FPGA and validation and computer simulation combining communication system will be greatly accelerated, rapid prototyping design part baseband, great place for real-time computation and show the algorithm has higher requirement of the validation. This paper based on FPGA realizing the digital signal modulation system implementation scheme by Manchester coding encrypted, by FSK digital modulation, and in the QuartusII software on the logical compiled,and reliability of the verification system.
