Abstract

A hardware/software system is described for the digital simulation of arbitrary point-to-point communication systems. This system makes extensive use of interactive computer graphics and includes a PDP-11/40 acting as host to a fast peripheral array processor. The user can configure a wide variety of communication systems from basic modules provided as system facilities. These facilities include; source coders/decoders, channel coders/decoders, as well as modulators/demodulators appropriate for a number of modulation strategies. In addition to additive white Gaussian noise (AWGN) channels, the simulator includes the ability to model impulsive noise channels as well as fading-dispersive channels typical of say HF or Tropospheric scatter channels. The communications simulator is being employed both to evaluate existing modem performance and to explore new modulation/coding concepts appropriate for military, commercial and space applications.
