Embodiment 1

[0058] An embodiment of the present invention provides a microwave communication device, such asfigure 1 As shown, the device includes: a frequency source 10, the local oscillator signal generated by the frequency source 10 and the baseband data signal are up-converted into a microwave signal and transmitted, or the received microwave signal and the local oscillator signal generated by the frequency source 10 are down-converted into Baseband data signal (can be converted by mixer), the microwave communication equipment also includes:

[0059] Phase jump acquisition unit 20, used to collect phase jump information of frequency source 10;

[0060] The processing unit 30 is configured to perform phase correction on the baseband data signal according to the collected phase jump information, so as to eliminate the influence of the phase jump.

[0061] When the microwave communication equipment is working, the user equipment converts various information to be transmitted into baseban...

Embodiment 2

[0076] The technical solution of the microwave communication equipment provided by the present invention is not only applicable to the indoor (or outdoor) all-in-one machine structure, but also applicable to the currently commonly used split structure. The microwave communication equipment with the split structure is used as an example for illustration below.

[0077] Such as Figure 5 As shown, the microwave communication equipment with a split structure, that is, the transceiver of the microwave communication equipment is located outdoors (that is, the outdoor unit 200, Outdoor Unit, ODU), and the modem and baseband interfaces are indoors (that is, the indoor unit 100, Indoor Unit, IDU).

[0078] The indoor unit IDU100 mainly demodulates and digitizes the received microwave signal to decompose the required signal; at the same time, it also modulates the digital signal to be transmitted into a signal that can be transmitted. IDU100 mainly includes baseband and intermediate f...

Embodiment 3

[0091] An embodiment of the present invention provides a method for eliminating the influence of phase jump in a microwave communication device, such as Figure 10 As shown, the microwave communication equipment includes: a frequency source, the local oscillator signal generated by the frequency source and the baseband data signal synthesize a microwave signal, and the method includes:

[0092] 101. Collect phase jump information of the frequency source;

[0093] 102. Perform phase correction on the baseband data signal according to the collected phase jump information, so as to eliminate phase jump effects.

[0094] In the method for eliminating the influence of phase jump provided by the embodiment of the present invention, by returning the phase jump information, and then performing phase correction on the baseband data signal according to the returned phase jump information, eliminating the influence of the phase jump, the phase jump can be constantly corrected. Monitorin...

Abstract

Disclosed are a microwave communication device and system, and a method for eliminating the effect of phase jumping, which relate to the field of communications, can radically eliminate the effect of phase jumping, improve the capability of the microwave communication device for resisting the phase jumping, and solve the problem that a code error occurs in the communication system because of the phase jumping of the microwave communication device. The microwave communication device of the present invention comprises: a frequency source, and further comprises: a phase jumping collection unit which is used for collecting the phase jumping information about the frequency source, and a configuration processing unit which is used for performing phase correction on a baseband data signal according to the collected phase jumping information, so as to eliminate the effect of the phase jumping. Also provided is a microwave communication system which comprises the microwave communication device as claimed in the present invention.

Description

technical field [0001] The invention relates to the communication field, in particular to a microwave communication device, a system and a method for eliminating the influence of phase jump in the microwave communication device. Background technique [0002] Microwave communication is the communication that uses electromagnetic waves with a frequency of 300M to 3GHz—microwave. Microwave communication does not require a solid medium, has a large capacity, good quality and can be transmitted to a long distance, so it is an important communication means of the national communication network, and is also generally applicable to various special communication networks. [0003] How to eliminate the influence of phase jump is one of the most important issues in the design of microwave communication system (microwave system). Phase jump refers to the phase / frequency jump of microwave equipment (microwave communication equipment) during temperature changes. Phase jump will cause ca...
