Abstract
The invention discloses a wideband receiver and a base station in a communication network. The wideband receiver comprises an Intermediate Frequency (IF) frequency control module, a frequency synthesizer, a mixer and an analog-to-digital converter (ADC). The IF frequency control module comprises an interference detector adapted to detect interference condition on at least one frequency band, and an IF frequency selector adapted to select an IF frequency based on the detected interference condition from the interference detector. The IF frequency is selected to avoid high interference mixed product of the mixer occurring in used channel. The frequency synthesizer generates an oscillator signal of the selected IF frequency, the mixer down converts a RF signal to an IF signal using the oscillator signal of the selected IF frequency, and the ADC converts the IF signal to baseband data.
