Abstract:
1. A system for selecting a signal channel of a radio frequency signal, comprising: an analog RF section configured to process an analog RF input signal to generate a first low IF digital signal and a second low IF digital signal, the first low IF digital signal substantially comprising a signal component and an image leakage, the second low IF digital signal comprising an image component and signal leakage; and a signal processing section comprising a complex LMS image rejection module and a complex digital signal channel select filter, the complex LMS image rejection module configured to reduce the image leakage in the first low IF digital signal and reduce the signal leakage in the second low IF digital signal, the complex digital signal channel select filter comprising a band selection module configured to select a signal channel of the first low IF digital signal and suppress channel components adjacent to the selected signal channel.
