Design for Telemetry Noise Lossless Data Compression Device

摘要：

In this paper, a sort of lossless data compression device is introduced. According to the characteristics of large amount noise parameters in the space telemetry system. After analyzing and comparing kinds of compress effect on different algorithms, LZ+ARC algorithm, combined to the hardware of DSP and FPGA, is chosen as chief algorithm to realize telemetry noise lossless data compression. The experimentation shows that the data handling capacity of the device can reach 500K byte and the compress ablate rate can be up to 60％ ～80 ％.1
