Abstract

High quality audio signal is supposed to be provided with low bit rate and low computational complexity in mobile communication system. This paper proposed a novel audio coding bandwidth extension method (BWE), which calculates high-frequency synthesis filter by using codebook mapping method, and transmits quantified gain corrections of high-frequency part. The preliminary test show that this method can provide comparable audio quality with lower bit consumption compared with AMR-WB+.
