Digital Communications System Evaluation: Design Developments in Pseudorandom Sequence Usage, Signal Conditioning and Timing Regeneration

The aim of this paper is to develop a series of designs which allow evaluation of several digital communication system design concepts. Circuits were developed and tested which deal with three central areas of concern in digital communication networks. They include random signal generation and detection, signal conditioning, and digital timing extraction. A pseudorandom sequence generator and correlator design form the basic digital channel. Bi-phase transmission coding and digital timing regeneration were later added to the initial channel. System performance was confirmed by inserting errors and measuring error rate
