MODELING A COMMUNICATION SYSTEM USING LINEAR CODES AND EVALUATING THEIR EFFECTIVENESS

The paper presents some methods of linear coding: NRZ-L (Non-Return to Zero Level), NRZ-M (Non-Return to Zero Mark), RZ-AMI (Return to Zero Alternate Mark Inversion) and Manchester code. On the NI ELVIS II+ and module Emona DATEx it was succeeded to realize the prototype of digital communication system and estimate efficiency of signal demodulation.
