摘　　要：毫米波通信因其可以提供更高的传输速率和系统容量受到了广泛关注。针对毫米波信道的频域非平稳性,提出了具有连续频率响应的毫米波信道模型。利用射线跟踪和实测数据相结合的方法实现路径功率参数估计,采用频域信道测量方法对不同频率下的视距和非视距路径功率进行实测分析。实测和仿真结果表明,结合实测数据的路径功率模型与实测值基本吻合,验证了所提模型的有效性。Millimeter wave communication has been widely concerned because it can provide higher transmission rate and system capacity. Aiming at the non-stationarity of millimeter wave channel in frequency domain, a millimeter wave channel model with continuous frequency response is proposed. The method of combining ray tracing and measured data is used to estimate the path power parameters, and the channel measurement method in frequency domain is used to measure and analyze the line-of-sight and non-line-of-sight path power at different frequencies. The measured and simulation results show that the path power model with the measured data is basically consistent with the measured values, which verifies the effectiveness of the proposed model.
