N2 - Multiband bandpass sampling techniques have been widely used in Soft Define Radio (SDR) systems. The performance of systems using bandpass sampling is highly affected by jitter effects. This work investigates jitter effects for multiband bandpass sampling systems, and proposes a receiver that applies a two-stage method for combating the jitter effect. At the first stage, a maximum likelihood pilot-aided algorithm is used to estimate and compensate the dominated jitter. Then, at the second stage, we exploit the oversampled property of the received signal and propose a decimate-and-average scheme to further mitigate the residual jitter effect. Simulation results show that the proposed system can significantly reduce the jitter effect.
