SOFTWARE SUPPORT FOR A STORED PROGRAM PCM DECOMMUTATOR
Peterson, Dwight M.
Telemetered data generated by missile systems has become increasingly complex with the inclusion of asynchronous data streams, variable word lengths, and discrete encoding. The display of this data for analysis purposes requires sophisticated equipment, usually designed with a programmable architecture. This paper describes software support that was developed for a stored program PCM decommutator. The software includes a cross assembler and supports downline loading of the decommutator from a host computer.

The Impact of Phase Noise in Digital Satellite Communications
Cuccia, C. Louis
Many military and commercial satellite communication links are being used which utilize standard or staggered QPSK. At bit rates below one megabit, these links operate in environments which produce two types of impairments–continuous and random--which determine the final bit error rate and data throughput. This paper will discuss the impact of random phase jitter which is a major impairment which can be contributed at every point in the link. This phase jitter can cause significant phase and timing errors at the receiver output and can even lead to drop-outs of key terminal equipments. The various sources of phase jitter will be discussed and related to system performance. Particular emphasis will be made of the contributions of scintillation and random atmospheric effects and by equipment malfunctions to phase noise which can cause not only periods of increase in bit and timing error, but also clock slippage and I/C reversal which can cause decoders description and demultiplexers to become inoperative. This paper will also include considerations of cochannel and adjacent channel interference on phase jitter.
