Research For A Universal Signal Processing Platform Based On Software Radio

With the rapid development of wireless communication technology, the demands on the wireless communications transceiver becomes higher and higher. The modern world is an information age, information transmission can be wireless also can be wired. The wireless communications technology quickly accessed in many areas with it's low cost, easy to carry and wireless. In order to meet market demands and user needs. then more and more technology emerged. At present. High-quality, broadband is the common goal, and communication frequency is increasing very quickly.So-called software radio, refers to A standard. modular structure, hardware platform, with various functions. while software to complete the A/D converter as broadband antenna, with full realization near. improving digital programmable. The ultimate purpose of software radio communications system is to make out the hardware system structure, through the software. The basic idea of this thesis is based on a set of universal hardware platform, With the universal hardware platform and programmable software structure, Soft Radio is designed to realize all kinds of functions of trans-receiver by software so that it can provide huge flexibility and maximal adaptability to meet the needs of connectivity and multimode. Especially in the military communication field, a kind of trans-receiver having functions of Soft Radio is an efficient measure to solve the communication problem in cooperating-battle under the condition of hiah science and technology.
