| Software defined radio is a new kind of wireless communication system,which has been developed in recent years.It will be a major change in military and commercial fields.As a new standard,software communication architecture has been recognized by various standards organizations in the aspects of intelligence,platform and standardization.However,with the increasing complexity of the system,the requirement of system integration is getting higher and higher.The traditional multi-channel SCA system is difficult to meet the requirements of high integration and configurability.This paper proposes that it design and implement the multi-channel SCA system by using the dynamic partially reconfiguration technology of FPGA.The SCA system with four channels is an example to study and discuss the FPGA waveform components by using the partial dynamic reconfigurable technology in detail in this paper.The main work of this paper is as follows:(1)The hardware and software architecture of SCA are analyzed,and the principle and implementation method of the local dynamic reconfiguration technology are introduced.(2)Hardware and software architecture of the system,system resource management and operation standardization environment are designed,and the system resources are allocated.(3)The structure and interface of FPGA waveform component are designed.the design of FPGA waveform reconstruction are researched by using the dynamic partially reconfiguration technology in the SCA architecture,and the waveform reconstruction were managed.It improves the system's scalability and dynamic configuration capability.(4)Finally,by verifying the function of the system,it is proved that the waveform reconstruction method of multi-channel SCA system is effective and feasible.It is proved that the use of dynamic partially reconfiguration technology can reduce the configuration time of the system and improve the flexibility and configurability of the system. |
