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 frequency detection method for recognition wireless communication is provided to stably perform frequency detection even though a noise environment is changed. CONSTITUTION: The output of a detector is obtained from a receiving antenna. A frequency is detected by combining the obtained L detector output. If the frequency detection method is a PRO(i1-iM), the detection probability of PRO(i,k) is obtained through a predetermined equation.

Abstract: PURPOSE: An Alamouti STBC applying method for enhancing performance of an offshore wind power radio communication control system is provided to apply a MIMO Alamouti STBC(Space-Time Block Coding) to a radio communication based control system, thereby improving transmission quality and reliability of the control system. CONSTITUTION: An Alamouti STBC applying method comprises the steps of: building multiple antennas using the overlay network technology; applying MIMO Alamouti STBC for optimal communication of the multiple antennas. When a control system operates normally, the control system processes valid data by interworking an up line with nets of odd numbers and a down line with nets of even numbers. When failing in forming a wireless link of the up line to a radio device in the front car of a train or detecting an error, the control system reads data of the radio device in the tail car for processing the data as valid data.
