High Data Rate ARTM Tier II Telemetry Waveforms Receiver Analysis and Design

Abstract

In this article we show how phase noise and demodulator complexity define the potential performance of high data rate telemetry receivers for ARTM continuous phase modulation (ARTM CPM) signals. Given a level of phase noise and demodulator complexity, we can predict the potential performance of a receiver. We also provide the results of actual receiver performance measurements (obtained using RCB-4000 Telemetry Receiver). We develop a simplified analytical model for an ARTM CPM signal transmission and present the resulting equation for phase increment difference between close signal sequences. The analysis of demodulator performance deterioration due to inter-symbol interference and due to receiver phase noise is then provided. Actual receiver phase noise data is included and is used to analyze demodulator performance.
