Signal processing method, receiving terminal equipment and transmitting terminal equipment

Abstract

An embodiment of the invention discloses a signal processing method, receiving terminal equipment and transmitting terminal equipment to improve flexibility of a narrow-band interference inhibition method. The method includes: a receiving terminal acquires first signals, wherein the first signals are signals transmitted in sub-bands within a receiving range of the receiving terminal and are signals in a UFMC (universal filtered multicarrier) waveform, and the sub-bands no less than two are obtained by splitting of preset wideband channels; the receiving terminal filters the first signals to obtain second signals; the receiving terminal subjects the second signals to AGC (automatic gain control) adjustment to obtain third signals; the receiving terminal judges whether the third signals meet preset conditions or not; if yes, the receiving terminal confirms that the third signals are free of interference; if not, the receiving terminal sends instructions to a transmitting terminal, wherein the transmitting terminal is a device which sends the first signals, and the instructions are used for indicating that the receiving terminal fails to complete filtering of interferences caused to the first signals. Consequently, flexibility of the narrow-band interference inhibition method can be improved.

Description

technical field [0001] The present application relates to the communication field, and in particular to a signal processing method, a receiving end device, and a transmitting end device. Background technique [0002] According to the regulations of the State Radio Regulatory Commission, the 223-235MHz frequency band has 480 available frequency points at intervals of 25KHz for power, military, water conservancy and other industries, so there are a large number of narrowband signals in the 223-235MHz frequency band, and if In the 223-235MHz frequency band, a broadband network is integrated, so the broadband network is often interfered by narrowband signals emitted by adjacent narrowband base stations. [0003] In the prior art, in a system environment where broadband and narrowband are integrated, the receiving end uses a filter with fixed bandwidth to filter the input signal in the broadband channel so as to filter out interference. [0004] However, due to the large number ...

AI Technical Summary

Problems solved by technology

[0004] However, due to the large number of narrowband interference signals in the system and frequent changes in frequency, it is difficult for the filter with a fixed bandwidth at the receiving end to effectively filter out interference, so the existing methods for suppressing narrowband interference are not flexible enough
