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. ...
