Abstract: This report summarizes techniques that use the measured instantaneous envelope statistics of arbitrary noise or interference processes to calculate the degradation these processes cause to digital communication systems. Computer implementation of the techniques are also given. The computer algorithms are designed for the data obtained from a general purpose noise measurement device, termed the DM–4 (for "distribution meter–model number 4") recently developed by NTIA/ITS. For illustration and for comparison with theoretical results, two noise examples are employed, one for "narrowband" interference, and one for "broadband" interference. These examples are taken from the noise models recently developed by Middleton.

Keywords: computer algorithms; digital system performance; non-Gaussian noise; system performance software
