20110270905 | METHOD AND DEVICE FOR PERFECTLY INCOHERENT SAMPLING TO A HAAR DOMAIN - The present invention relates to a method for converting a signal, including the steps of: providing a first representation of the signal in a first domain; converting the first representation of the signal into a second representation of the signal in a second domain, by applying a transform involving a Haar transform and a Hadamard transform, such that a basis of the second domain is maximally incoherent to a Haar basis. The signal is converted to a domain whose basis is maximally incoherent to a Haar basis. Yet, it is not required to convert the input vector representing the signal to a Haar basis first. This allows reducing the number of steps which increases conversion efficiency. Accordingly, obtaining the structure of the signal requires fewer samples. | 11-03-2011 |
