In this paper, we investigate the performance enhanced transceiver design in a Device-to-Device (D2D) communication system underlaying a cellular network. The problem of joint transmitter and receiver optimization via maximizing the entire D2D and cellular transmission rate is considered. Due to the non-convexity of the primal problem, we resort to decomposing the problem into a sequence of standard...
The paper applies the method of the artificial fish swarm algorithm for the coordinated design of the PSSs in a real large-scale power system, in order to increase the damping of power system oscillations. The AFSA method is briefly introduced in the paper firstly. Then the optimized parameters of the PSSs are obtained by solving the objective optimization problem by using the AFSA method. Finally,...
Motion recognition via trajectory is important in motion analysis for many robotic tasks. A descriptor for motion trajectories plays an important role in the recognition algorithm. Existing invariant descriptors and discrete matching algorithms are not flexible enough under certain circumstances for recognition. In this paper we propose a new descriptor to solve this problem, with a modified data...
This paper proposes a digital background calibration algorithm for pipelined analog-to-digital converters (ADCs). The algorithm doesn't modify pipeline stages and only needs simple calibration logic. Based on the analysis of the output codes, the algorithm estimates the bit weight of each stage and calculates the outputs. To verify the algorithm, a 13-bit pipelined ADC with 1.5-bit/stage architecture...
A statistical analysis using subspace perturbation expansion is applied to the direction of arrival (DOA) estimation bias for MUSIC, Min-Norm, ESPRIT, State-Space Realization (TAM), and Matrix-Pencil algorithms, assuming that only a finite amount of array data is available. The authors obtain an unified analytical expression of the DOA estimation bias for those algorithms in a simple and self-contained...
