Abstract


With the constant increase in the integration of communication system, the complexity of the project development is also growing and the traditional design and examination method of system will not meet the project’s requirements. Thus, the architecture design based on Software Communications Architecture(SCA) and Component-based Development Research will bring forward a new technology architecture and development process for the design of complex integrated system. As one of open Software Radio criterions, SCA defines interface and function of software and handware components in communication system. Following SCA architecture, makes software radio communication system relize component development. Developers define components and link ports to achieve waveform development and application deployment.First, this article simply introduces SCA and expatiates the basic concept, such as Core Framework(CF), CORBA and Hardware Abstract Layer(HAL) and so on. In order to research the development and implementation of the waveform based on SCA and realize the transplanted and reconfigured waveform component, this article designs a universal hardware platform which can load and run the various application components. At present, the waveform based on SCA has not been applied on specialized hardware(DSP、FPGA) in home. According to the supplementary standard of hardware of SCA3.0, this paper makes special hardware enter into SCA architecture through the realization of HAL and proxy component.Then, this paper introduces in detail the overall structure of univeral hardware platform, workflow design and the achievement of every functional circuit. Then the main components of the selection and power estimation are described. Due to enormous SCA system and complicated traditional development process, to make development process more agile and directviewing, according to the requirement of waveform component implementation, the general method of developing waveform based on SCA by using integrated development environment (CE) is summarized and put forward, Which make SCA system development much more convenient. On the basis, component modeling was completed on the CE platform. Meanwhile, MSK modulation and demodulation waveform components were divided and the function of components was designed on FPGA. Then according to the SCA Hardware Supplement criterion, the design of FPGA HAL was completed and the implement methods of proxy component were given.At last, the MSK waveform was loaded on the hardware platform and waveform function was validated. The testing results show that the system developed by this method meets the SCA criterion and has merits, such as reuse and dynamic configuration, improving waveform’s reusability, interoperability, and Ability to dynamically deploy. The whole developed process may have some reference to drive the application of the waveform based on SCA in project.
