“…This is because altering feeding port indices greatly changes the impedance matrix Z A , Z AP and Z P in (37), making the problem (41) complicated to solve. To overcome this difficulty and meet these constraints, we propose the use of the alternating optimization method to iteratively optimize the load reactances and selection of the feeding ports [36], [37].…”

A method for achieving the continuous-space electromagnetic channel capacity bound using loaded N -port structures is described. It is relevant for the design of compact multiple-input multiple-output (MIMO) antennas that can achieve channel capacity bounds when constrained by size. The method is not restricted to a specific antenna configuration and a closed-form expression for the channel capacity limits are provided with various constraints. Furthermore, using loaded N -port structures to represent arbitrary antenna geometries, an efficient optimization approach is proposed for finding the optimum MIMO antenna design that achieves the channel capacity bounds. Simulation results of the channel capacity bounds achieved using our MIMO antenna design with one square wavelength size are provided. These show that at least 18 ports can be supported in one square wavelength and achieve the continuous-space electromagnetic channel capacity bound. The results demonstrate that our method can link continuous-space electromagnetic channel capacity bounds to MIMO antenna design.

“…The basic mechanism for topology independent routine is to generate algebraic structures by address computation thus forming logic linkages between the nodes in the network for routine programming to guarantee the efficacy of data routine. In some existed cases, some specific nodes, generally central, sink or leader, are required to perform the programming or scheduling for hop-based routine task [15] [17]. Therefore, most topology-dependent distribution protocols need to carry out based on leader election, which needs more resources to perform the computation task.…”

Abstract-In this paper, we share our recent work related to Radio Frequency Identification (RFID) sensor network with readers. The work mainly focus on the protocol for network system to perform the task of autonomous decentralized data distribution with consideration of economic and low-power RFID-sensor module scheme. We analyzed data pitfall in distributed RFID-sensor network, revealing the reason lies in the phenomenon. A distributed solution to tackle the problem has been designed in a simple way. The test results show that the system with proposed approach provides an efficient and more balanced in data distribution which proves the protocol is feasible for the application scenario.Index terms: RFID Sensor network, equal probability scheduling, stochastic switching, Galton effect.

“…With the rapid development of science and technology, indoor positioning technique is becoming more and more important, for example, mobile robot localization, intelligent conference, garage localization, store localization and so on [1][2] [3]. Because of the fact that Global Position System(GPS) can only be used in outdoor places [4][5] [6], other techniques also need to be researched to realize the goal of accurate indoor localization.…”

The requirement for specific indoor location is more and more pressing. However, traditional approaches can only achieve a low accuracy. In this paper, we put forward a new approach to evaluate the target position with the acoustical Linear Frequency Modulation Signal(LFM). Comparing with other acoustical approaches, it is robust to noise, and most importantly it can realize a high accuracy and a good real-time performance. Besides that, several innovative location methods are also compared and verified to promote the real-time, accurate and robust performance.
