Embodiment Construction
[0014] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings, so that those skilled in the art can better understand the present invention. It should be noted that in the following description, when detailed descriptions of known functions and designs may dilute the main content of the present invention, these descriptions will be omitted here.
[0015] The existing signal modulation methods cannot meet the functional requirements of simultaneous transmission of telemetry, remote control, and communication signals in one signal in the unified system of measurement and control communication. The present invention proposes a signal fusion method based on dimension expansion, which can fulfill the functional requirement of simultaneously transmitting multiple functional signals in one signal. The present invention expands the definition domain of trigonometric functions to complex numbers to establish the corresponding...

The invention discloses a signal fusion method based on dimension expansion. The signal fusion method is used for expanding a traditional time diversity and frequency diversity system into a dimension diversity system. Different signals are transmitted by utilizing different dimensions which are mutually and independently orthogonal. Transmission of a plurality of paths of data at the same time and under the same frequency is realized; signal amplitudes and bit rates of each path of signals are not restricted by the fusion method. According to the signal fusion method, a real number field is expanded into a two-dimensional complex number field; a virtual number field is expanded into a virtual number two-dimensional space and a virtual number three-dimensional space, even higher dimension; a dimension expansion method with a recursive property is utilized, and dimension expansion with different degrees can be carried out on the signals according to actual requirements, so that the signals with different varieties are transmitted by different dimensions through a certain manner; transmission of multifunctional signals of detection, measurement and control, communication, navigation and the like is realized, and the multifunctional signals do not interfere with one another.
Description
technical field [0001] The invention belongs to the technical field of information processing, and more specifically relates to a signal fusion method based on dimension expansion. Background technique [0002] The traditional information support system based on a separate functional architecture, the inherent defects of single function and insufficient make it unable to adapt to the needs of current and future air-space-ground integrated information comprehensive support and comprehensive strategic space development. In today's and future air-space-ground integrated information interconnection, the information support system not only provides important support and guarantee for the flight of aerospace vehicles, but also is the lifeline of the launch, flight, and recovery stages of aerospace vehicles; The anti-jamming transmission of mission control commands transmits reconnaissance information back and interacts with information on other functional platforms in real time to...
