Abstract

To process broadband signals and analyze their power spectrum, it is necessary to consider the parallelization, accuracy and system complexity of processing. In this paper, a wideband signal power spectrum analysis method based on Fast Fourier Transform (FFT) is proposed and implemented on the platform of Field Programmable Gate Array (FPGA). This method realizes the FFT of high-speed serial signals by parallel computing, so it can realize the power spectrum analysis function of signals when the sampling rate is much higher than the processing rate. At the same time, according to the processing characteristics of FPGA IPCore, two real FFT operations are realized by one complex FFT operation, so as to minimize the resource utilization. This paper completes the simulation analysis on Matlab, and implements it on the hardware platform of EV12AQ600 ADC and Xilinx xc7vx690tffg1927-2, and finally presents the consistent results of the two.
