英文摘要：

Channel measurement is one of the most effective and direct ways to obtain the channel characteristics. With the increasing of measurement bandwidth, the improvement of measurement accuracy and the richness of measurement indexes, eliminating the system response in wireless channel measurement process becomes an important step not to be neglected. In this paper, the effect of the system response of the channel sounder on objective physical channel is investigated, and a theoretical method of eliminating the system response of the channel sounder is proposed. Based on the laboratory-emulated and realistic site measurement data, the feasibility of the proposed method is verified. Meanwhile, the objective factors affecting the system response of the channel sounder and the influence of sampling dispersion on the channel impulse response are analyzed.
