Abstract:

Software defined radio technology is widely used in military and civilian radio communication because of its flexibility and openness. Using computer, MATLAB, FPGA and ADIs AD9364 radio frequency (RF) agile transceiver, we design a signal testing platform for different mobile communication systems with varied characteristics, including WCDMA, TD_SCDMA, GSM and LTE. The testing platform can generate arbitrary digital sine waves, analyze the information of communication signals in real time and adjust the parameters of RF chains. Experimental results show that the communication signal testing platform is in accordance with the principle of software defined radio, and it has good versatility, portability and reconfigurability.

Key words: software defined radio, FPGA, MATLAB, radio frequency agile transceiver
