| Time Reversal(TR) technology has attracted wide research because of its unique temporal and spatial focusing, and Ultra Wide Band(UWB) is also a hot spot in current wireless communication area. In order to reduce the high Bit Error Rate (BER) caused by multi-path effect, a novel technology combine TR with UWB is proposed.Wireless Sensor Network (WSN) is attributed as one of the key technologies in next generation, but its performance is restrained by the limited energy of nodes. Therefore, the application of TR into the energy transmission for WSN is proposed to recharge the nodes wirelessly.According to the studies, in this paper, a platform for the simulation of information/energy transmission in UWB communication system/WSN based on TR is designed and developed in VC++, MFC and OpenGL are also used. This platform mainly functions as 3-D electromagnetic modeling, electromagnetic simulation, UWB communication simulation and WSN simulation. Also, a good Graphical User Interface (GUI) is established, in which, every module is independent of any other and can be combined to accomplish integrative simulations.Finally, several examples are simulated to test the platform. The temporal and spatial focusing of TR is testified by the single pulse transmission simulation using FDTD. By the communication system (SISO, SIMO, MISO) simulation results, it is proved that TR can improve the UWB communication performance significantly. And by the WSN simulation of information and energy transmission, we witness the potential to use TR in WSN to realize wireless recharge to the nodes. Through the test results, we come to the conclusion that all the functions are achieved as expected and the tiny difference in simulations proves the reliability of the platform. |
