Systems Engineering: Optimization on Stiefel Manifold for MIMO System
نویسندگان
چکیده
Applications of multiple input and multiple output (MIMO) with Stiefel manifold are growing in the next generation communications and their system engineering developments. These applications need to be optimized efficiently with less complexity and cost. In this research, optimization problems in MIMO systems using Stiefel manifold are considered. As far as general manifolds are concerned, optimization methods are applied in a different environment that deals with basic signal processing. Here, specific optimization technique, which can be applicable in current MIMO system with Stiefel manifold, is given as a methodology. The current MIMO system is a new technology, and it can be applied in the next generation technology because it uses manifolds in feedback of MIMO systems. Even though, overall performance of new and current technology is better than conventional techniques, final performance of MIMO applications is anticipated with efficient optimizations. Keywords-Stiefel manifold; MIMO system; optimization; Feedback.

متن کاملStiefel Manifold and TCQ based on Unit Memory Coding for MIMO System
The Multi Input and Multi Output (MIMO) systems have been analyzed with a number of quantization techniques. In this short communication, few problems like performance and accuracy are investigated through a quantization technique based on Stiefel Manifold (SM). In order to improve these problems, suitable Trellis Coded Quantization (TCQ) based on Unit Memory (UM) coding is studied and applied ...

Time-delay identification is one of the most important parameters in designing controllers. In the cases where the number of inputs and outputs in a system are more than one, this identification is of great concern. In this paper, a novel autocorrelation-based scheme for the state variable time-delay identification for multi-input multi-output (MIMO) system has been presented. This method is ba...
متن کاملGlobal optimization on Stiefel manifolds — some particular problem instances ∗
Optimization on Stiefel manifolds was discussed by Rapcsák in earlier papers. There, some numerical methods of global optimization are dealt with and tested on Stiefel manifolds. In the paper the structure of the optimizer points is given in some particular problem instances and for a special form of a quadratic problem defined on a Stiefel manifold. Some reduction tricks and results are obtain...
