Embodiment Construction

[0025] The specific implementation manners of the present invention will be described in further detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] like Figure 1~5 As shown, the present invention provides a kind of aviation channel simulator, comprises channel simulation unit and man-machine interaction module;

[0027] The channel simulation unit is used to simulate the data through the ray tracing method to obtain the simulation result (the function of the ray tracing module) of the aviation channel after receiving the aviation data from one of its ports, and then utilize the simulation result to construct the traditional aviation channel. Obtain the statistical channel model (the function of the traditional module) by modulus; It is used to obtain the real-time received signal through the ray tracing method a...

Abstract

The invention discloses an aviation channel simulator and a simulation method, belonging to the modeling field of aviation channels. The aviation channel simulator comprises a channel simulation unit and a human-machine interaction module, wherein the channel simulation unit is used for simulating data with a ray tracing method to obtain the simulation result of the aviation channel after aviation data is received from one port of the simulation unit; then the traditional aviation channel is modeled by the simulation result to obtain a statistics channel model; after the other port receives a transmission signal, a real-time receiving signal is obtained with the ray tracing method so as to obtain the real-time response data of the channel; the statistics response curve of the traditional aviation channel is obtained from the transmission signal by the statistics channel model; and the human-machine interaction module is used for displaying the statistics response curve and the real-time response data of the channel. According to the aviation channel simulator and the simulation method, the aviation channel is efficiently, accurately and quickly modeled with low cost.

Description

technical field [0001] The invention relates to the field of aviation channel modeling, in particular to an aviation channel simulator and a simulation method. Background technique [0002] Aviation communication plays an important role in the national economy. It has become a trend to transmit multimedia services in the future aviation communication network. People have considered using various technologies including multi-carrier technology to improve the system capacity of aviation communication. But first, the problem of channel measurement must be solved. The channel model is also very important for studying the modulation, equalization and coding performance of a wireless channel. [0003] The aviation channel simulation is significantly different from the channel simulation in the ordinary environment. The channel measurement in the airborne environment is in a narrow, long and limited space environment, which is far from the traditional statistical model. For channe...
