The Design Of Cognitive Radio Hardware System Platform And The Interface And Data Transmission

The appearance of Cognitive Radio technology is the most effective way to solve the tension spectrum that highly used in the future. It fully reflects that we can use the spectrum in maximum way. So we expand the frequency space in disguise. Build a cognitive radio test platform not only has important theoretical significance but also has practical value.This article describes an overview of cognitive radio and the design of hardware and interface. By using a Xilinx's large-scale logic programmable device Virtex-5 and a TI's high-performance dual-core chips TMS320DM6467 which includes a C64 + DSP and an ARM9 chip. This design implements a hardware-based experimental platform for cognitive radio and detailed the hardware and software debugging. The platform is universal and flexible. Data flow and management is flexibility through software control. Structure different communication systems to meet the research needs.
