METHOD AND APPARATUS FOR MEASURING FREQUENCY COMPONENT

摘要

A frequency component measuring method includes a step of generating a second vector group with a maximum energy concentration characteristic at a certain frequency using a first vector group; a step of detecting the certain frequency from an inputted communication signal using the second vector group as a base matrix for compression sensing; and a step of measuring components existing at the detected certain frequency.
