Abstract

The invention discloses a method for the simultaneous common-frequency work of a plurality of pieces of electromagnetic equipment in a single carrier. By the method, a plurality of pieces of equipment in the single carrier with a finite area or volume can simultaneously transmit and receive electromagnetic waves to normally communicate with the outside under the conditions of same working frequency range and partial overlapping or adjacency. Digital interfaces and analogue interfaces are required by each piece of equipment, and are connected with one another for the transmission of transmitted signals of each piece of equipment. The influence of the transmitted signals on received signals can be eliminated by analogue interference suppression and digital interference suppression in a receiving flow of each piece of equipment. By the method, a frequency spectrum utilization rate can be greatly increased, requirements for a clutter and harmonic outer-of-band rejection technology can be lowered, and difficulty in system upgrading and expansion can be lowered.

Description

technical field [0001] The present invention relates to multi-device communication. Specifically, the present invention relates to multiple devices in a system with limited area or volume communicating with the outside at the same time at the same frequency. Background technique [0002] In a system with limited volume or limited area (such as aircraft, aircraft carrier, and missile), there are multiple devices that emit and receive electromagnetic waves, such as communication equipment and navigation equipment. Since each device is in the same frequency band, and the working frequency points of some devices overlap, the effective transmission signals and heteroharmonic signals of each device are very easy to enter the receiving channel of other devices. Cross-modulation, inter-modulation, strong signal suppresses reception of weak signal, etc. Usually, the sensitivity of the device will be reduced, the bit error rate will be increased, and the performance of the device wi...
