Non Uniform Sampled signal reconstruction for software defined radio applications

摘要

This paper focuses on digital reconstruction methods of uniform signal from its non uniform samples. A specific Non Uniform Sampling (NUS) technique for controlling Analog-to-Digital Conversion (ADC) in a multi-standard radio receiver is presented. Several reconstruction algorithms are summarized and a general mathematical formula is used to describe these algorithms. Different methods are classified into two types: iterative and interpolation methods. For radio communications context, performances in terms of accuracy of reconstruction and computational complexity, are shown and compared for these algorithms.
