In this paper, the quadratic-programming (QP) based scheme-formulation is employed to handle the joint-angle-drift problem of a redundant three-link planar robot arm with its end-effector moving along different types of trajectories (e.g., a Lissajous-figure path, a triangular path and an elliptical path). The physical constraints such as joint limits and(More)
—In this paper, we focus on the radio resource management (RRM) in heterogeneous networks with orthogonal frequency division multiple access (OFDMA), and aim to maximize the system sum-rate and meet quality of service (QoS) requirements under the proportional fairness constraint of user rates. The previously proposed resource allocation schemes, which do(More)
—This paper models compact MIMO system recurring to microwave network. theory. Using scattering parameter matrix (S-Matrix), it analyses the ability of suppressing mutual coupling effect and power exporting ability of compact MIMO antenna arrays. Simulations have been done on four different types of antenna arrays which respectively are parallel double(More)
In view of the great potential in parallel processing and ready implementation via hardware, neural networks are now often employed to solve online matrix algebraic problems. Recently, a special kind of recurrent neural network has been proposed by Zhang et al, which could be generalized to solving online Lyapunov equation with time-varying coefficient(More)
