Design and Spurious-free Dynamic Range Analysis of a Compressed Sensing Wideband Receiver
摘要
Abstract
In order to analyze the performance loss and application of compressed sensing wideband receiv-er,the design detail of a compressed sensing receiver is provided based on modulated wideband converter ( MWC) structure. Simulations and experiments are performed to measure the spurious-free dynamic range ( SFDR) of the receiver. The result shows the large SFDR loss of the receiver caused by the non-orthogo-nality of dictionary atoms. When compressed at the ratio of 1/2,the SFDR of the compressed sensing wide-band receiver is about 7 dB,which will severely limit its application in high dynamic range requirements.关键词
