Damage Identification of Frame Structures Based on Compressed Signal Processing
type: item
description: In view of the huge amount of data generated in the process of structural health monitoring and the huge burden on data storage, a structural damage identification method based on compressed sensing is proposed. This method first reduces the dimension of the original signal by means of compressive perception theory and characterizes the original damage signal by replacing the original signal with the compressed signal. Then, the compressed signal is wavelet packet decomposition and damage identification is performed by constructing energy eigenvectors. In order to better reflect the advantages of compressive perception applied to structural damage identification, the processed compressed signal is compared with the original signal for damage identification. A three-story reinforced concrete frame is simulated by finite element software ABAQUS, which is verified by the damage identification method and numerical examples. The results show that the proposed method can accurately identify structural damage using compressed signals and obtain more accurate recognition results while reducing the computational load.

Research Progress and Application of Approximate Computing Technology in Digital Signal Processing
type: item
description: Approximate computing technology has attracted significant attention in the field of signal processing. Complex algorithms and massive data volumes have limited processing speeds and increased hardware consumption in various applications. However, due to the redundancy of signals, precise results are not always necessary, and acceptable results for users are often sufficient. Therefore, the adoption of approximate computing technology can effectively reduce computational load, improve computational efficiency, and enhance system performance. This paper delves into different design levels of approximate computing technology. Firstly, it introduces the characteristics of signal processing applications. Then, it reviews recent research progress in approximate computing technology at both the algorithmic and circuit levels. Additionally, it explores approximate computing solutions in signal processing areas such as communications, video imaging, and radar. Finally, the paper discusses and provides an outlook on the future development directions in this field, offering insights to promote the application of approximate computing technology in signal processing.
