Abstract: In order to study and verify cognitive radio techniques and algorithms, an embedded cognitive radio platform is proposed. The platform uses dual-processor architecture of ARM+FPGA. It is divided into three parts of RF, baseband processing and embedded control. As main processor, ARM runs the embedded Linux system and is responsible for the work of system control as well as the work of interaction. As data processing core, FPGA is responsible for the baseband signal processing, algorithms and RF module configuration. The platform is used flexibly with LCD touch screen. It can work without PC. It provides a good hardware platform for the study of the cognitive radio technology.

Key words: cognitive radio, embedded system, ARM processor, FPGA processor
