Pulse code modulation telemetry - Properties of various binary modulation types
Abstract
The present investigation is concerned with a comparison of the performance of methods for the transmission of digital data, taking into account aspects of performance under simulated range conditions. Attention is given to radio frequency spectra, bit error rate performance, peak carrier deviation, premodulation filtering, receiver IF bandpass filtering, receiver/demodulator video bandwidth, pulse code modulation (PCM) codes, phase shift keying, and four major methods for recording PCM signals. It is found that pulse code modulation/phase modulation (PCM/PM) signals can achieve better data quality than pulse code modulation/frequency modulation (PCM/FM) signals with the same radiated power if wide bandwidths are available.
