Abstract:
The article describes the two-stage lossless compression method for telemetry data, in which the linear prediction method acts as a decorrelator in the first stage, and Rice codes act as an entropy coder in the second stage. A detailed description of implementing linear prediction is presented and applied in experiments on different telemetry frame structures, in the Inter-Range Instrumentation Group (IRIG) standard 106 format. Telemetry data analysis is performed, and compression efficiency is presented based on estimates of the gain in variance and entropy of the output signal from the decorrelator. Based on the experimental results, conclusions are extracted, and recommendations are suggested.
