Abstract. Time-variant discrete multiple-input multiple-output systems with a regular discrete time intervals of separate channels are considered. A method of analysis of process quality in such systems is presented. Scalar evaluation of the vector processes in the systems are realized by singular value decomposition of special matrices. The method feasibility in evaluation of the system performance is demonstrated by majorant and minorant estimates of generally accepted indicators of quality. Algorithmic maintenance using Sylvester matrix equation with variable matrix components is constructed with the account of the discrete nature of the time-variant multiple-input multiple-output systems.
Keywords: multichannel systems, time-variant discrete systems, separate channels, regular discrete time intervals, singular value decomposition, scalar evaluation of processes quality
