Investigations of the Carrier recovery in digital modems by analytic models and practical measurements
Abstract
Decision feedback carrier recovery loops are described by linear models leading to relatively simple relationships. Numerical evaluations of the derived expressions are compared with practical measurements, which were carried out in real-time operation using a flexible experimental system for data transmission over telephone lines.
