Problems solved by technology

[0012] 1) Since the clutter signal is an in-band signal, this method cannot distinguish CCI from the clutter signal;
[0013] 2) Since this method usually only detects out-of-band interference, it cannot distinguish ACI from other out-of-band interference;
[0014] 3) The design of its integrated circuit is very complicated, and the power consumption is large,

Example Embodiment

[0103] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0104] In the field of communications, time slicing technology is a time division multiplexing technology. Its working principle is: the transmitting end divides all data into several pieces and encapsulates it, and transmits a data packet to a certain receiving end in a specific time slice. In this time slice, the data packet will occupy all the data bandwidth alone. At the same time, the data packet also includes the arrival time of the next data packet. For the receiving end, it only needs to receive the next data packet at the time specified by the data packet. However, energy-saving processing can be done in other idle time, so that the power consumption of the handheld terminal will be significantly reduced, which greatly reduces the power con...

Abstract

The invention discloses an interference signal detection method which is suitable for a receiver; in the method, the band width of an I-path filter and a Q-path filter of a tuner is adjusted in an idle time that the receiver does not carry out data transmission, so as to carry out ACI and CCI interference detection; in addition, the band width of the tuner is adjusted according to the result of the interference detection, so as to control on/off state of the ACI filter and CCI filter in a demodulator; in a time slicing that the receiver receives a data package, the data package is received. The invention further discloses a receiver with an interference detection function. By applying the invention, on the premise of not affecting the data transmission, the ACI/CCI detection is realized and the integration cost is reduced.

Description

technical field [0001] The invention relates to interference detection technology, in particular to an interference signal detection method and a receiver with interference detection function. Background technique [0002] In a communication system, interference is an important factor affecting communication quality. Interference includes: adjacent channel interference (ACI: Adjacent-Channel Interference), co-channel interference (CCI: Co-Channel Interference), clutter signal (spur), and the like. [0003] In existing communication systems based on time slicing technology, the following two methods are usually used for interference detection: [0004] The first way: RF RSSI (RF RSSI: Radio Frequency Received Signal Strength Indicator) and baseband received signal strength indication (BB RSSI: Base Band Received Signal Strength Indicator) for the tuner integrated circuit (Tuner IC) and some hardware Compare to determine out-of-band interference. This method is real-time. ...
