Due to a great many redundancy symbols, most of the existing differential space-time-frequency (DSTF) coding schemes suffer very low transmission rates. To overcome the disadvantage and obviously enhance the total transmission rate in a differential multiple-input-multiple-output (MIMO) orthogonal-frequency-division-multiplexing (OFDM) system, a rate embedded doubly directional DSTF coding scheme...
In this paper, we propose a novel codebook-based precoding design for orthogonal space-time block codes (OSTBCs) over multiple-input multiple-output (MIMO) channels with finite rate feedback. The proposed approach aims at providing better system performance by utilizing the property of OSTBCs and the prior information of the statistical antenna correlation. Under a new way of controlling the average...
In this paper a novel learning control law is proposed which can obtain learning gain matrices from a recursive identifier along the learning axis. This algorithm convergence is proved with random noise disturbance. The control law can online regulate learning gain matrices along the learning axis by using RLS technique and doesnpsilat need system accurate model. Finally it is applied in pneumatic...
