Theoretical preconditions for development of perfect communication channels "small satellites -earth"

Anatolij Płatonow

Abstract

The paper discusses the possibilities to improve reliability and quality of data transmission over forward channel "small satellite (ST)-ground base station (BS)" using adaptive feedback communication systems (AFCS). The main advantage of AFCS as compare to the known CS is their capability to transmit both analog and digital signals "perfectly" that is with a bit rate [bit/s] equal to the capacity of the forward channel ST-BS, maximal accuracy, and fixed bit error rate (reliability). The perfect AFCS are narrowband systems transmitting signals in real time with the energy [J/bit] and spectral [bit/s/Hz] efficiencies attaining the limit values established by information theory. The source of these advantages is replacement of coding units by the analog modulators adaptively adjusted by controls delivered to ST from BS over high-quality feedback channels. The latter one simplifies a construction of the ST transmitters, as well reduces their energy consumption, cost and sizes. Moreover , adaptive properties of AFCS permit to maintain the perfect mode of transmission during overall time of the contact between the satellite and BS. The aim of the paper is presentations of theoretical basis enabling a development and application of improved (perfect) AFCS for ST-BS communications. The presented results are confirmed in experiments with hardware prototype of the perfect AFCS. Apart from the basic and new material , paper presents a genesis of research and explains the reasons of absence of AFCS in modern communications.
