It is well known that multiple-input multiple-output (MIMO) wireless communication systems that employ multiple transmit and receive antennas can provide very high-rate data transmissions. We study an ARQ-BLAST scheme and use turbo codes as FEC. Based on the research, an ARQ-BLAST system with adaptive error control is presented in this paper. It provides(More)
In this paper, a scheme is extended to study numerical doubly periodic solutions of the Kortweg-de Vries (KdV) equation with initial conditions using the Adomian decomposition method. As a result, we obtain the numerical doubly periodic solutions of the KdV equation with initial conditions. The numerical doubly periodic solution is compared with the exact(More)
In this paper based on a system of Riccati equations with variable coefficients, we presented a new Riccati equation with variable coefficients expansion method and its algorithm, which are direct and more powerful than the tanh-function method, sine-cosine method, the generalized hyperbolic-function method and the generalized Riccat equation with constant(More)
In this Letter, we study (2 + 1)-dimensional Boussinesq equation and (3 + 1)-dimensional KP equation by using the new generalized transformation in Homogeneous Balance Method (HBM). As a result, many explicit exact solutions, which contain new solitary wave solutions, periodic wave solutions and the combined formal solitary wave solutions and periodic wave(More)
First, a Q-S (lag or anticipated) synchronization of continuous-time dynamical systems is defined. Second, based on a backstepping design with one controller, a systematic, concrete, and automatic scheme is developed to investigate the Q-S (lag or anticipated) synchronization between the drive system and response system with a strict-feedback form. Two(More)
Typically wireless multi-hop ad hoc and sensor networks utilize protocols that relay packets hop-by-hop along a path connecting source node to sink node. The emerging cooperative routing (CR) methodology, however, can obtain distinct performance gain by selecting extra relay to forward data. This study presents a novel distributed weighted cooperative(More)
Using symmetry analysis we systematically present a higher-dimensional similarity transformation reducing the (3+1) -dimensional inhomogeneous nonlinear Schrödinger (NLS) equation with variable coefficients and parabolic potential to the (1+1) -dimensional NLS equation with constant coefficients. This transformation allows us to relate certain class of(More)
In this paper, we study chaos (lag) synchronization of a new LC chaotic system, which can exhibit not only a twoscroll attractor but also two double-scroll attractors for different parameter values, via three types of state feedback controls: (i) linear feedback control; (ii) adaptive feedback control; and (iii) a combination of linear feedback and adaptive(More)
