Abstract: PURPOSE: A method for determining position coordinates of an OpenVG-based multi layer overlapping part is provided to reduce the computation of time scale conversion by performing normalized cross-correlation computation for a small range based on a predicted optimal movement point. CONSTITUTION: Time scale conversion for a first frame based on a WSOLA(Waveform Similarity Overlap-and-Add) algorithm is performed after an input speed is initialized. An optimal movement point of the next frame is predicted using an estimated pitch. Normalized cross-correlation computation is performed for a small range based on the predicted optimal movement point. A pitch change of a voice signal between frames is detected using a normalized cross-correlation threshold value.

Abstract: PURPOSE: An authentication key distribution method of a sensor network system is provided to reduce the transmission of unnecessary information by monitoring a network state. CONSTITUTION: A base station(110) stores sensor information by collecting the sensor information from one or more cluster heads(120). The base station calculates an authentication key distribution restriction distance by applying a fuzzy algorithm to the stored sensor information.

When the necessity of the authentication key distribution is requested, the cluster head transmits the authentication key using the received authentication key distribution restriction distance.

Abstract: PURPOSE: An interference elimination method of a frequency wireless repeater in a marine telematics environment is provided to control a step size of an LMS(Least Mean Square) filter by estimating a channel state of a feedback signal. CONSTITUTION: A channel state of a feedback signal is estimated based on an output signal of an LMS filter. The feedback signal is eliminated by controlling the step size of the LMS filter based on the estimated channel state of the feedback signal. When the power change of the output signal is rapidly changed as time passed, the channel state is determined as fast fading. When the power change of the output signal is slowly changed as time passed, the channel state is determined as slow fading.
