SYSTEM PERFORMANCE EVALUATION UNDER SIMULATED LINK ERROR CONDITIONS

Abstract

This paper is concerned with the concept and development of cost effective methods for determining sensor-to-user system performance under simulated real world conditions. Many system elements involved in the digital pre- and post- processing functions found in telemetry systems are designed to operate primarily on error free data. The presence of bit errors drastically alters the performance of these elements: data compressors pass noise, E.U. converters produce subtle and wild data variations, and embedded voice channels become overly noisy. This paper identifies the digital areas affected by noise in modern systems, categorizes their susceptability, and suggests laboratory simulation techniques that may identify problems prior to mission data flow.
