Abstract:During the recovery procedure

modulated wideband converter

a recently proposed sub-Nyquist sampling method

uses continuous to finite block to get the support set

which suffers high computational complexity

and thus slows down the recovery rate. So

a new method based on measurement vectors transform

called MVT

to get the support set is proposed. By integrating the continuous variable

it transforms infinite measurement vectors model into single measurement vector model

and then uses proven methods to solve single measurement vector model and to get the support set. Transforming infinite measurement vectors model into multiple measurement vectors model suffers high computational complexity

and slows down the whole recovery rate. This is avoided by MVT. And also

solving multiple measurement vectors model is more time-consuming than solving single measurement vector model. The experimental results show that MVT increases the recovery rate at least three times under appropriate number of sampling data.
