Description

Technical Field

[0001] The utility model relates to the technical field of co-channel interference cancelers, and specifically relates to a co-channel interference canceler. Background Art

[0002] Co-channel interference refers to the interference caused by the carrier frequency of the useless signal being the same as that of the useful signal to the receiver receiving the co-channel useful signal. A co-channel interference canceler is a device that can simulate the interference signal and cancel it to achieve interference suppression.

[0003] However, the existing co-channel interference cancelers have the following disadvantages:

[0004] (1) The existing co-channel interference cancelers have relatively weak fixing functions. When in use, in the prior art, the canceler is usually placed on the surface of an object during installation. Since it is not easy to disassemble after being fixed, the steps are cumbersome and it will cause wear to the device.

[0005] (2) The existing co-channel interference cancelers have relatively weak buffering functions. When in use, since the canceler needs to be continuously debugged and carried according to the signal, it will be damaged when colliding during the carrying process. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a co-channel interference canceler to solve the problems raised in the above background art.

[0011] Optionally, a body is provided at the bottom end of the pressing plate, and the body is a canceller.

[0012] Optionally, the limiting plates are oppositely distributed on the top end of the placing plate.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. For the existing co-frequency interference canceller, through the settings of the placing plate, limiting plates, bolts and pressing plate, during use, by placing the canceller on the surface of the placing plate, the limiting plates are used to limit the canceller, and turning the bolts can drive the pressing plate to press and fix the four corners of the top end of the canceller.
