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...
This paper presents a way to utilize the sub-sampling technique for spectrum sensing in cognitive radio applications. The proposed receiver utilizes a bank of band pass filters and a high speed analog to digital converter/sample and hold, which can be dynamically tuned to a specific sub-sampling frequency using an adjustable frequency source. This type of architecture requires fewer RF components...
