Asymmetric millimeter wave and submillimeter wave wireless channel simulation method

Abstract

The invention discloses an asymmetric millimeter wave and submillimeter wave outdoor channel simulation method, and relates to the field of wireless communication. According to the method, the characteristic that the channel distribution environment shows asymmetry is fully considered, the millimeter wave and submillimeter wave channel simulation method is designed, and millimeter wave and submillimeter wave wireless channel impulse response and parameters under the asymmetry condition can be generated through adoption of the method. Channel impulse response is divided into a sight distance path, a single hop and a double hop by combining the propagation characteristics of air molecule absorption and rough surface diffuse scattering of millimeter waves and submillimeter waves, so that parameter description and channel simulation of uplink and downlink channels are accurately realized. And moreover, the correlation of the asymmetric uplink and downlink channels is fully utilized, so that the complexity of channel response and channel parameter generation is effectively reduced, and the practicability of the method in system simulation verification application is enhanced. The method can be applied to design and deployment of an asymmetric millimeter wave and submillimeter wave communication system, and theoretical and model bases are provided.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to an asymmetric wireless channel simulation method in millimeter wave and submillimeter wave frequency bands. Background technique [0002] With the continuous development of the information society, future post-5G and 6G mobile communication systems will need to meet higher requirements in terms of data rate, delay, and coverage capabilities. The current frequency band resources with lower frequencies are almost already occupied by various communication services and become extremely crowded, and it is difficult to excavate available spectrum resources. The millimeter wave and submillimeter wave frequency bands have large and continuously available bandwidth, which can meet the data transmission rate of hundreds of Gbps and the delay requirements of hundreds of microseconds in the communication system. Moreover, the wavelength of the millimeter wave and the submillimeter wave...
