Digital System Performance Software Utilizing Noise Measurement Data

摘要

The 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.
