Abstract
A method for determining a representation (y) of a signal (s) comprise selecting a predetermined number (m) of row vectors (v1, . . . , vm) from a predetermined measurement matrix (M). The predetermined measurement matrix (M) is predetermined dependent on a product of a predetermined Hadamard matrix or generalized Hadamard matrix (H) and a predetermined representation matrix(B). The predetermined representation matrix (B) represents a predetermined basis for the signal(s). The method further comprises determining a respective inner product of the signal (s) and each of the predetermined number (m) of selected row vectors (v1, . . . , vm) resulting in a predetermined number (m) of measurements (y1, . . . , ym) forming the representation (y) of the signal (s).
