Research on Lossless Data Compression Technology
The implementation of data compression technology can be divided into software compression and embedded hardware compression. The software compression operation is large, requires large data buffer space, and does not have real time performance. This does not meet the requirements of real time transmission of telemetry system; embedded hardware compression overcomes the above shortcomings of software compression and is widely used in telemetry systems. Data compression is divided into lossy compression and lossless compression. The high reliability and data accuracy of the aerospace telemetry system determine that only lossless compression can be used to facilitate the analysis of data by technicians and make correct judgments.
