Optimization of subsampling dual band receivers design in nonlinear systems

This paper presents an optimization of the noise performance for a dual band receiver based on subsampling in a nonlinear scenario. The focus is on designing a multiband receiver for software defined radio. Thus, another goal of the presented architecture is its flexibility, focusing on the jitter and folded noise optimization of the subsampling receiver and covering as many wireless standards as possible. To approach these objectives, different architectures based on subsampling technique are investigated and analyzed.
