Prototype of analog feedback communication system: First results of experimental study

The paper presents first results of an experimental study of narrow band optimal analog adaptive feedback communication system (AFCS) designed for analog signals transmission. The prototype system implemented optimal transmission — reception algorithm derived and studied in [1]-[4] and other author's works. The aim of the study was a comparison of theoretically expected performance of the system (limit accuracy, power and bandwidth efficiency of transmission) and performance provided by its hardware implementation.
