Research On The Precise Channel Simulation Of The Full Duplex System

With the developmen of technology, communication resources are becoming increasingly short sup-ply. Current deployed wireless communication systems employ either a time-division or frequency-division approach to bidirectional communication. This requires dividing the temporal and/or spectral resources into orthogonal resources and results in half-duplex wireless communication systems, which limit the development of wireless communication systems. In order to improve the utilization, full-duplex system has recently be-come a focus. In the design of full-duplex system, self-interference should be get to eliminate the interference sign from the received signal. When the system is located in multipath fading channel, the path attenuation and path delay is necessary to realize the system.This paper studies full-duplex wireless communication systems which consist on same band and simul-taneous bidirectional communication. Leapfrog ADI-FDTD method and a new ABC is used to simulate the channel between the antennas.At first, the development of full-duplex wireless communication systems and its models are shown in Chapter 1. Then the approaches (FDTD method) is determined by comparing the most popular electromag-netic algorithms(MoM, FEM and FDTD). Then, the formulation of FDTD, ADI-FDTD and leapfrog ADI-FDTD is introduced to make preparation for the program in Chater 2. The leapfrog ADI-FDTD method is chosen for its better performance. In Chapter 3, a new kind of ABC’s is developed to get better performance. At last, in Chapter 4, the experimental results further show the correctness and excellent performance of the program and the channel characteristic parameters are get from the response in time domain.
