A digital hardware platform for RF PA digital predistortion algorithms
Digital pre-distortion technique is one of the most crucial techniques used to solve frequency distortion in wireless communication links, which is due to nonlinear behavior of devices like power amplifier and limits frequency bandwidth of signal. This paper introduces a multi-function digital platform employed to verify and test different digital pre-distortion algorithms. The digital platform is mainly comprised a FPGA chip Xilinx Zynq-7000 (XC7Z030), an integrated transceiver chip ADI AD9361, and external digital interfaces such as HDMI, Ethernet network and fiber-optical. Processes needed by digital pre-distortion including A/D, D/A, and digital down conversion can be achieved in real time adjusted by software. Its working frequency bandwidth is from 70MHz to 6GHz, with instant frequency bandwidth up to 56MHz. The final pre-distortion results can be exhibited in video with graphical form.
