Embodiment Construction

[0021] In order to effectively improve the accuracy of the simulation of system interference coexistence, the embodiment of the present invention provides a dynamic simulation method for system interference coexistence. The method includes: for each system link in the mobile communication system, set At each set time point within the time length, determine the measured signal-to-noise ratio of the system link at that time point, and obtain the measured signal-to-noise ratio according to the determined measured signal-to-noise ratio and the set signal-to-noise ratio threshold interval The modulation and coding scheme corresponding to the threshold interval of the signal-to-noise ratio is located, and the transmit power of the mobile communication system is controlled according to the acquired modulation and coding scheme corresponding to each system link at least one time point. Since in the embodiment of the present invention, the modulation and coding mode of each system link ...

Abstract

The invention discloses a dynamic simulation method and a dynamic simulation device aiming at coexistence of system interference, which are used for solving the problem that a simulated result obtained by static simulation in the prior art is not close to that of an actual system and inaccurate. The method comprises the following steps of: determining a measurement signal-to-noise ratio on each time point of each system chain and a modulation coding manner corresponding to a signal-to-noise ratio threshold value interval where the measurement signal-to-noise is positioned on the point of time, and controlling emission power of a mobile communication system according to the acquired modulation coding manner corresponding to each system chain on at least one point of time. In the embodiment of the invention, the modulation coding manner of each system chain is adjusted according to the currently determined measurement signal-to-noise ratio of each system chain, and the emission power of the mobile communication system is controlled by the adjusted modulation coding manner; consequently, so that the mobile communication system adopting a self-adaptive coding manner makes the simulated result more accurate and closer to that of the actual system.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a dynamic simulation method and device for system interference coexistence. Background technique [0002] Multi-system coexistence generally refers to the situation where two or more wireless networks work simultaneously in the same area. In the study of multi-system coexistence, the degree of mutual interference of wireless signals between different systems and the measures to reduce interference for different interference degrees are mainly studied. [0003] In the prior art research on the coexistence of mobile communication systems and radar systems, the research methods used include deterministic analysis methods and simulation methods. The deterministic analysis methods are mainly for analyzing the interference between base stations, and this method is mainly used for analyzing the interference between base stations. Interference in the "worst" case, the sim...
