This paper presents a modified rank-reduction (RARE) method for joint direction-of-arrival (DOA) estimation and gain-phase calibration with some partly calibrated uniform linear arrays. Through recursively building up RARE matrices, the proposed method can guarantee the estimated gain-phase coefficients being unique, so as to improve the stability of gain-phase calibration performance. Another advantage...
This paper is concerned with the consensus control problem for a network of high order linear continuous-time agents subject to communication delays between neighbouring nodes in the network. Departing from the common practice which firstly designs the consensus control under the delay-free assumption and then computes the maximally tolerated communication delay, we propose a new simple technique...
“Data century has arrived! Having too many applications to discrete mathematics rather than use continuous mathematics, the method instead of using analog to digital methods. The vector and matrix has become the language which we must speak up.” says the author of the professor named Gibert, S. Linear algebra is a branch of mathematics that studies the object is a vector, a vector space (or linear...
In the condition of single training sample, traditional methods get low recognition accuracy, or even can not be used. In view of this situation, this paper proposes a method to slove this problem. Firstly, face image is decomposed by image pyramids. Then, each layer image segmentation into sub images with th same size. After that, the feature of each sub image, which got with (W2DPC)2A, gets a weight...
Space-time algorithm based on cyclic correlation matrix is introduced and the cyclostationarity of signals is taken into account. Numerical simulation shows that it can considerably improve the performance of the software defined antenna and therefore be widely used in variant fields.
The targeted and current development of wind energy in various countries around the world reveals that wind power is the fastest growing power generation technology. Squirrel cage induction generator has been widely used in the wind power industry. However, with the increment in penetration of these turbines, power system will experience a change in dynamics and operational characteristics. Given...
The canonical 4-D Chua's circuit is a special one of the higher dimensional Chua's circuits and can realize every eigenvalue of four dimensions. This paper studies hyper-chaos in this circuit in two cases: one is applying the three-segment odd symmetrical piecewise-linear resistor; the other is applying the two-segment piecewise-linear resistor. The dynamical behaviors of the circuit are investigated...
In this paper, the bilateral interdigital coplanar waveguide (CPW) slow wave line is studied. The slow wave effect is obtained by the capacitively loaded structure with a symmetrical interdigital line loaded on the both sides of the central line. This kind of the slow wave line can be regarded as a periodic guided wave structure. As a result, in order to accurately analyze this periodic structure,...
