Algorithm Analysis and Application of Digital Signal Processing Technology

Digital signal processing is a rapidly developing field of science and technology. In the 1960s and 1970s, it experienced the development stages of digital filtering theory, signal Fourier transform, convolution and fast correlation calculation. Subsequently, the rapid development of computer technology and microelectronics technology promoted the development of digital signal processing technology and pushed it to a climax. Algorithm analysis is the study of algorithms. An algorithm is a set of rules that explain how to solve computer programming problems. The most common algorithm is the search and sort algorithm, which tells you how to find what you need in a large group of items. It is also used to search files or databases, group data, or find patterns in a dataset. The method adopted in this paper is to use FPGA to complete the signal preprocessing and STFT algorithm implementation. The necessary parameters and data results obtained from FPGA processing are transferred to DSP through the interface in a handshake manner, and the DSP completes the subsequent modulation analysis and parameter estimation. This method is much more efficient and reliable than using DSP alone to complete all processes in the past, and greatly shortens the cycle of intra pulse analysis.
