Abstract

The invention discloses a strong transient signal data compression method, and the method comprises the following steps: (1) analyzing lossy compression and lossless compression algorithms; (2) analyzing lossy compression and lossless compression effects; (3) combining lossy compression and lossless compression methods to realize adaptive data compression. The objective of the invention is to solve the problem that sampling frequency and measurement parameters increase data storage pressure. And meanwhile, multi-parameter and high-density composite signals are subjected to optimized storage. The method has the advantages that several mainstream data compression methods are utilized, and a data compression scheme of strong transient signals is explored. Data is divided into stable data anddynamic transient data by identifying strong transient signals, and on the basis, lossy and lossless compression effect research is carried out on the data. And finally, dynamic adaptive data compression is performed on the process data. Therefore, the problem of data storage is solved.

Description

technical field

[0001] The invention relates to a data compression method, in particular to a strong transient signal data compression method. Background technique

[0002] In today's electronic information technology field, a digital revolution with long-term impact is taking place. Since the data volume of digitized multimedia information, especially digital video and audio signals, is extremely large, it is difficult to obtain practical applications without effective compression. Therefore, data compression technology has become a key common technology in today's digital communication, broadcasting, storage and multimedia entertainment.

[0003] Strong transient is a kind of non-uniform distribution signal relative to the smooth signal. Its generation is often accompanied by strong energy release, high-frequency vibration and high background noise, and at the same time causes a series of changes in the momentum and attitude of the object. Non-uniform, non-stationary, an...
