The Research Of Software Radio Transmission And Reception System

According to the requirement of smart antenna within the country, basing on the conceive of "software realize of multi-system compatible", we analyzed the capability of the wireless signal in different conditions, the manage and research method, through this research we connected the software radio technology and antenna array technology together and then realized the smart antenna technology with dynamic collocate of antenna character.We concentrated on the key technology of software radio digital interface, including digital frequency conversion, conversion of sample ratio and the channel wave filtrate, designed the realization method of the base digital interface which meet the requirements of GSM and UMTS and described the base theory that will be used during software radio conversion design and the discipline that should be followed, basing on these basal theory and design discipline, choosing multi-system, we completed the design of the transmission and reception.
