Problems solved by technology

[0002] With the continuous upgrading of wireless communication networks and the rapid development of the Internet of Things, the number of wireless communication networks of various frequency bands and standards has increased sharply, the electromagnetic environment of wireless networks has become increasingly complex, and the in-band interference problems encountered by wireless network equipment have also become more and more serious. These have brought serious challenges to the normal use and maintenance of wireless networks
[0003] The existing method is to solve the problem of in-band interference by improving the sensitivity of the receiving equipment and reasonable network planning and reducing the performance of the network
The problem caused by the existing method is that the performance of the wireless network cannot be brought into full play, the maintenance cost of the wireless network is high, and the service quality of the network is not good. It is imminent and imperative to receive in-band interference cancellation devices for adaptive wireless transceiver systems

Abstract

The invention discloses a device for receiving in-band interference in a wireless transceiving system with an adaptive counteracting function and a counteracting method. The function of the device isas follows: a transmission signal of a signal coupled from a radio frequency transceiving channel is filtered by a wave trap, and then divided by an amplification and power division device, one signalreaches a counteracting circuit after being delayed, the other signal which is the same as an in-band receiving signal and generated by a receiving signal generation unit is counteracted with an original receiving signal at the counteracting circuit, a data processing unit adjusts an amplitude and phase modulation device according to the size of the signal detected by the receiving signal detection circuit until the received signal is less than a preset value, the amplitude and phase of the interference signal are counteracted by a data processing unit according to the size of the detected in-band receiving interference signal, and adjusted inference signal is fed into a main receiving channel to counteract an in-band interference signal in the main channel, and thus the problem of in-band interference of the main channel is solved. According to the device and method provided by the invention, the received in-band interference signal can be adaptively counteracted according to the variation of the receiving interference signal, and the deficiency that in traditional ways, only the in-band interference of a certain fixed frequency point can be solved via the wave trap is overcome.
