Abstract :
A method is described for quantifying the signal-to-noise ratio degradation due to aperture jitter in IF sampling receivers given the statistics of the input signal. In the absence of such an analysis, aperture jitter is often incorrectly specified. The emphasis is placed on CDMA receivers using automatic gain control, but the method is also applicable to FDMA technologies. Results presented may be used to specify aperture jitter in receivers utilizing the IF sampling topology.
