Abstract
Disclosed in the present application are a method for improving performance of a low-intermediate frequency receiver, a storage medium, and a receiver. The method comprises: selecting a local oscillator signal from a preset local oscillator frequency set as an initial local oscillator signal to perform frequency mixing processing on an input signal, so as to obtain a low-intermediate frequency signal comprising a low-intermediate frequency useful signal and a low-intermediate frequency interference signal; determining whether an energy ratio of the low-intermediate frequency interference signal to the low-intermediate frequency useful signal is greater than a first preset ratio; and if the energy ratio is greater than the first preset ratio, selecting another local oscillator frequency from the preset local oscillator frequency set as the current local oscillator signal to process the input signal. In this way, the present application can improve the adjacent channel selectivity of a low-intermediate frequency receiver.
