请英语高手翻译一下这段摘要！谢谢！很急

By simulating a paper introduces the background of mobile wireless networks, use a powerful network modeling and simulation tools, to have OPNET -- the mobile wireless network simulation network model and operation simulation, finally through the view of bit-error-rate and throughput, compares the two kinds of different types of antennas, the performance of network, and that which is more conducive to improving antenna model of the mobile wireless network performance. This article first introduces the part in the introduction of the network simulation, network simulation of software and its simulation method Secondly, to have the mobile wireless network simulation analysis, design of it. Third, introduces the wireless network model of mobile system simulation is realized. Include network model of the process, system simulation results, and check the corresponding statistics and analysis, etc.
