A NOVEL PHASE MODELLING TECHNIQUE AND APPARATUS I THE CONTEXT OF SINUSOIDAL TRANSFORM CODING OF ACOUSTIC SIGNALS

Andreas Spanias (Inventor)

Research output: Patent

Abstract

With the virtual explosion of cellular voice communication along with the impending conversion of such communication from analog to digital modes, there is a very real problem of the communications bands failing as a result of them being overwhelmed with data. Consequently, the need to compress the acoustic signal data down to a level that is manageable and that will allow information to flow freely without danger of the system breaking down due to overloads.Researchers at Arizona State University have invented both a method and a device that relies on sinusoidal wave modeling to effectively analyze the acoustic signal at the point of transmission and then re-synthesize the signal at the receiving end. This allows for the information to be transmitted effectively while minimizing the actual acoustic signal; thereby preventing the signal band from being overwhelmed.This technology has obvious application in cellular voice transmission as well as other potential applications such as in voice recognition, multimedia data compression, etc.
