基于FPGA的并联DC-DC电源系统无线发射装置的设计

Parallel design DC-DC power supply system of the wireless transmitter device based on FPGA

在无线传输的系统设计中,越来越多的使用到了DSP+FPGA的方案,由FPGA做时序控制,而DSP做复杂的算法处理,这样的分工可以使二者各尽其能,使整个系统的性能最优。本文分别从基带和射频前端两方面对无线发射装置进行硬件设计,重点研究的是基带DSP与FPGA的接口设计和超外差架构射频前端FPGA对本振、A/D或D/A的动态配置。最后自编程序证明该方案行之有效,且具有一定的通用性和灵活性。

In the wireless transmission system design, the use of more and more to the DSP ＋ FPGA, sequential control by the FPGA, and DSP do complex algorithm processing, the division of labor can make his each can, make the optimal performance of the whole system. This paper respectively from two aspects of baseband and rf front-end to hardware design of wireless transmitters, the key research is the baseband DSP and FPGA interface design and the superheterodyne structure of rf front-end FPGA this vibration,A/D or D/A dynamic configuration. Finally self-programming proves that the scheme works, and has a certain commonality and flexibility.
