| Summary: | International Telemetering Conference Proceedings / October 24-27, 1983 / Sheraton-Harbor Island Hotel and Convention Center, San Diego, California === The Communications Interface Equipment is a multi-link communication subsystem
designed to augment the command and telemetry capabilities of the Space Shuttle and its
payloads. One link consists of two PSK channels which are frequency division
multiplexed. In each channel the data can be at one of several possible data rates and
either NRZ or Bi0/ encoded. Simultaneous operation of the two channels causes a
performance degradation to each due to mutual interference. The amount of degradation is
a function of modulation formats, data rates, relative channel powers, probability of error
and bandpass filter characteristics. Approximations for the degradation are derived, and
the performance sensitivity to the various parameters is demonstrated. |
