Hardware And Software Implementation Of Mobile Wireless Channel Simulator

As an important part of wireless communication, wireless communication channel will be researched. Wireless communication channel is one of typical kind, of time-varying channel, and it has great theoretical significance to research and simulate the signal with the propagation characteristics of the wireless communication channel, which is also supposed to have much practicability.In this paper, a DSP and FPGA based wireless communication channel is designed and implemented based on the concerned theory on the effects caused by the transmission of radio wave. Firstly, this article expounds the important character of wireless channel, and then we establish a mathematic model. Then the hardware platform of this model is detailed described. At last, the implementation of software is given combining with some experiment results. Testing results show that this type of simulator is able to simulate the signal transferred in real wireless communication channel restricted to narrowband providing with the main characteristics of multi-path propagation, Rayleigh fading, Rice fading etc. Furthermore, it can be performed with low cost and easy operation comparing with other congeneric products.
