A Novel Mobile Audio Bandwidth Extension Algorithm Oriented 3G Communication

As the complexity of the 3G mobile communications environment, the limitation of the wireless transmission frequency band resources, in order to achieve the transmission and reconstruction of low bit rate, high-quality audio signal, a modified EAAC+ mobile audio coding algorithm based on the existing technology of speech or audio bandwidth extension research is presented in this paper. The algorithm can reduce the computational complexity, and ensure the tone quality of reconstructed audio signal by detecting and removing the sinusoidal component of short transient signal.
