Application Of DSP In Software Radio Technology

Software radio is a new wireless communication architecture put forward in the early 90th of 20 century. It is an important innovation in wireless communication. Software radio technology realizes various communication functions through installing different software on a universal open radio platform. Software radio system is applicable to multiple frequency bands and it can change working mode flexibly. The system can interwork and is compatible with various equipment of different system and standard. First, the thesis introduced conception and characters of software radio; Second, the thesis analyzed architectures of software radio; Third, the thesis discussed critical technologies of software radio and applications of DSP in software radio, moreover, realized arithmetic of CRC coding , convolution code, orthogonal digital frequency conversion and multi-speeds signal process; Finally, the thesis prospected foreground of software radio.
