Embodiment Construction

[0021] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. It should be noted here that the descriptions of these embodiments are used to help understand the present invention, but are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not constitute a conflict with each other.

[0022] This specific implementation mode discloses a method for generating a sea area evaporative waveguide channel. Specifically, using the spatial multipath channel (SCM) model as an example, the channel described by the following formula needs to be generated in the simulation:

[0023]

Abstract

The invention discloses a method for generating channel of sea area evaporation duct. The waveguide channel generation is realized through the steps of parameter setting, ray propagation type discrimination, formula rewriting, hop number discrimination, formula solution, angle discrimination, parameter calculation and channel generation. The advantage of the method is that the channel parameters of the statistical arrival paths are brought into the channel generation module to form the evaporation waveguide channel. By using the actual parameters of each arrival path of the waveguide layer receiver, which are usually only simple real numbers, a fast and effective numerical method is used instead of the complex parabolic equation calculation to reduce the time required to generate the channel and the complexity of generating the channel. The applicability of the optical ray method is enhanced so as to generate evaporation duct channels which are more suitable for the actual situation.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for generating a sea area evaporation waveguide channel. Background technique [0002] With the continuous growth of the marine economy and the increasingly active marine activities, the demand for mobile communications in sea areas has shown exponential growth. In order to meet the needs of future mobile communication applications, it is necessary to develop high-speed, wide-coverage, and low-latency sea area communication services. Offshore areas can use land base stations for topological network coverage, but due to the limitation of the curvature of the earth, there are still a large number of communication blind spots in far-sea areas. Although satellites can be used to cover these remote areas, personal terminals cannot afford the high cost of satellite communications. [0003] Atmospheric ducting is a natural phenomenon with great development potential in the field of ...
