摘要：

A ring parallel computation system with four FPGAs is implemented to select and track complex and dense signals in real-time. Two FPGAs perform 1K-1M points Fast Fourier Transform or Inverse Fast Fourier Transform (FFT/IFFT). Another FPGA distills the parameters of the signal in the time and frequency domain and manages the whole system as well. The fourth FPGA manages the interfaces. This system can accomplish many works such as signal conversion between time and frequency domain, signal parameter selection in the frequency and time domain, and etc.
