A WAVELET PACKET TRANSFORM-BASED APPROACH FOR INTERFERENCE MEASUREMENT IN SPREAD SPECTRUM WIRELESS COMMUNICATION SYSTEMS

Leopoldo Angrisani

Abstract

The paper mainly concerns interference measurement in spread spectrum, wireless communication systems. A new digital signal-processing method is proposed, which proves non intrusive and independent of the specific system considered. Thanks to the nice properties of the wavelet packet transform, the method is capable of extracting the occurred interference from the spread spectrum signal, thus ensuring accurate interference magnitude and frequency estimates also in critical conditions: interference level much smaller than that characterizing the spread spectrum signal, and interference spectral content very close to the carrier centre frequency of the considered system.
