%X This paper presents a novel technique for directly IF sampling and digitally obtaining the inphase (I) and quadrature (Q) components of the IF signal. Because all subsequent processing and detection are accomplished in the digital domain, it can provide even more unproved I and Q signals and improve the overall performance greatly. Finally an experimental scheme is provided.
