    摘要： Provided are a data transceiver and method for performing equalization and pre-emphasis adaptive to the transmission characteristic of a transmitting part. The transceiver measures the signal attenuation characteristic of a transmission line of a receiving part using an input data signal input via the transmission line of the receiving part, decodes the distorted waveform of the input data signal, distorts the waveform of an output data signal beforehand using the measured signal attenuation characteristic of the transmission line of the receiving part, and transmits the output data signal via a transmission line of a transmitting part. Thus, when the output data signal is transmitted via the transmission line of the transmitting part, the waveform of the signal remains optimized.

    摘要： Disclosed is a technique for localizing a sound source. In the technique, a sound pressure signal measured by microphones is acquired using a spherical microphone array sensor where the microphones are fixedly arranged on a surface of a spherical body. A sound pressure distribution on the surface of the spherical body is obtained by a controller from a sound pressure calculation formula for calculating a sound pressure at a certain location of a spherical surface using the sound pressure signal measured by the microphones as an input value. A location of the sound source is estimated from the obtained sound pressure distribution.
