Abstract:Construction principles for algorithms intended to perform space-time and turbo processing of signals and to improve the qualitative characteristics of high-rate data transmission systems have been discussed. The algorithm for space—time processing of signals transmitted by the system with several transmitting and several receiving antennas—which relies on the analysis of principles applied to the construction of known transmission systems with high spectral efficiencies and makes it possible to enhance the reliability of information transmission without deteriorating the system throughput—is proposed. A new iterative algorithm for signal processing at the receiver has been developed to implement the advantages of the proposed method of space—time processing of signals. The results of computer simulation that confirm the great potentiality of proposed algorithms are presented.
