Abstract: PURPOSE: A sound model compensation method which combines mask based multi-channel sound separation for marine sound is provided to analyze noise and voice properties, thereby improving performance of voice recognition. CONSTITUTION: A noise model and a weighted value necessary for sound model adaptation are obtained by using an HMM based mask. Mask information is estimated from a binaural signal. Noise is decreased by using the mask. After MMSS(Mask-based Multi-channel Source Separation) is performed, a 13th MFCC(Mel Frequency Cepstral Coefficient) is extracted from a voice signal.

Abstract: PURPOSE: A buffer management method in a mobile IP(Internet Protocol) network for ocean telematics is provided to manage TCP flows which passes through a congested base station by using a base station packet buffering method. CONSTITUTION: It is determined whether a portable terminal is moved to a congested base station of a sub-network. When the portable terminal is moved to the congested base station, influence on TCP flows is confirmed by considering hand-off arrival distribution in the congested base station. The TCP flows passes through the congested base station by using a predetermined base station packet buffering method. A buffer is managed by a drop-tail method and an RED(Random Early Detection) method according to the hand-off arrival distribution.
