The Design of FPGA+DSP-based High-speed Baseband Signal Processing Platform

Aimed at the current issues of wireless communication system baseband signal processing platform, such as single function, poor flexibility and weekly operational capability, we proposed an enhanced hardware design scheme on the foundation of traditional processor architecture. This scheme adopts the processing of FPGA + DSP architecture, with high-performance devices and high speed interfaces, built a high performance general baseband signal processing platform. The platform achieves the processing intermediate frequency digital signal directly, and it combines digital upconversion, downconversion with baseband algorithms, In addition, the platform has advantagesSonSmodularization and flexibility. Experimental results demonstrate that the platform of baseband processing can receive and process all kinds of baseband signal in time, and the data processing capacity has achievedStheShigherSlevel.
