Maodv Based On SCA Waveform Applied Research And Implementation

Software Defined Radio(SDR) has been the trend of the research and development of radio, and its core idea is to provide a software system which can enable reuse and reprogram of common blocks on an universal hardware platform, so as to deal with the traditional inconsistent communication systems and solve the cooperating communication problems. The development cost and cycles of communication system will be infinitely reduced due to the SDR software module development characteristics.The Software Communication Architecture (SCA) is an open architecture based on SDR, and it specifies the Software Architecture, Hardware Architecture and Security Architecture of software defined radio, and the Application Program Interface (API). SCA utilizes the idea of modules changeable to improve the co-operation of SDR and achieve that the modules between SDRs can be portable and reusable. At the same time, SCA meets the commercial and military requirement.The waveform application development of SDR is one part of SDR development based on SCA. The waveform application development is mainly to all kinds of existing waveforms,and the waveform application can be developed separately, so that the waveform application can be loaded on any SDR and the portability of this application can be realized.This paper conforms to the Software Communication Architecture Specification, analyzes the architecture of SCA,especially the software architecture. This paper also studies the method of waveform application development base on SCA. Through the development of the MAODV waveform application's API and middleware CORBA, the modularization of MAODV waveform application components finally have been accomplished, and the MAODV waveform application can be loaded on any SCA compliant SDR.
