The Design And Realization Of Point To Multipoint Wireless Communication System

With the high development of wireless communication technique and subscriber's requirements, regardless at public and military wireless communication application field, it is necessary to find a better system, which can satisfy to face to dispersion, big region, moderate capacity and tree-like in shape. So point-to-point is exactly the effective method to solve above problems. This system is adopted FDD and TDMA techniques to carry out point-to-point communication system.In this article, it is aim to introduce demonstration, manufacture and development of point-to-point wireless communication system. Firstly, analyze the character of wireless communication channel. Secondly, make demonstration and analysis about the selection of some key techniques, such as full duplex mode, anti-interference method, demodulation mode etc. and present a integrity project, which refers to the principle and implement of modulation and demodulation unit, baseband signal processing unit and radio unit .thirdly, prove the net-setup function by system testing at lab and field condition, and get multiway delay parameters and transmission loss at moderate relief; and fall condition. Finally, give a summary account and expectation about research and implement of point-to-point wireless communication system.
