摘要： There are provided a receiver in human body communication system using multiple receivers reducing an error rate of receiver signals by applying a space diversity acquisition-related SIMO technology to a plurality of received data using multiple receivers or receiver electrodes in a human body communication system using a human body as a medium, and of stably transmitting the data for the interference of signals generated by other users or from different electronic devices, and a method for receiving data in the human body communication system. The receiver and the method for receiving data in a human body communication system may be useful to stably transmit/receive data without any reduction of its transmission rate by reducing the distortion in channels and the signal noise which are caused in the use of one receiver.

摘要： A Time Division Duplex (TDD) communication apparatus and an operation method thereof can provide operation clock signals in the transmission and reception of the TDD communication apparatus using a Clock Recovery & Data Retiming (CDR) circuit, thereby stabilizing an operation without any crystal oscillator and reducing the power consumption. In a transmission time interval, a transmitting frame is processed using a clock signal of a reference frequency generated from the CDR circuit. In a reception time interval, a receiving frame is processed using a clock signal recovered from the receiving frame by the CDR circuit.

摘要： Provided are an apparatus and method for transmitting sound through a nonlinear medium. The apparatus includes a pre-distorter for previously distorting a sound signal to compensate for distortion to be caused by a frequency characteristic of the nonlinear medium in a transmission process of the sound signal, a sigma-delta modulator for modulating the pre-distorted sound signal into a signal having two signal levels, a high-frequency modulator for multiplying the modulated signal by a carrier wave having a higher frequency than an audio frequency band to shift the modulated signal to a carrier frequency band and generate a high-frequency modulated signal, and a transmitter for converting the high-frequency modulated signal into a sound wave signal suited to be transmitted through the nonlinear medium and transmitting the sound wave signal.

摘要： A technique for simultaneously acquiring vehicle identification information and speed information of an RFID tag-attached vehicle by calculating the vehicle speed by using a Doppler shift value extracted from transmission and reception signals between the RFID tag and the RFID reader is disclosed. A method for measuring a vehicle speed by using an RFID reader installed right up on the road or at the roadside includes: transmitting a continuous wave; receiving a reflected wave with respect to the continuous wave from an RFID tag attached to a vehicle which has received the continuous wave; extracting a Doppler shift value from the continuous wave and the reflected wave; and calculating the speed of the vehicle by using the Doppler shift value.
