Design and Implement of a Channel Model Based on TD-LTE

Abstract:

This paper studies the characters of wireless fading channel based on TD-LTE, and it is critical of multipath effect and Doppler effect. So there design a math channel model combining these factors. And then set up link in Matlab to analyse the model. Through simulating we can optimize the model. After that it is implemented by FPGA of final determined math channel model. Using TD-LTE baseband signal as driven signal, this model is simulated and implemented in ModelSim platform. Through comparison and analysis the error between the channel impulse of the model and the result of Matlab link, we can obtain that the relative error is very little. So it can confirm reliability of this channel simulator.
