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： Provided are a frequency modulation/demodulation apparatus using a frequency selective baseband and a transmitting/receiving apparatus using the same. In a frequency selective baseband transmission technique or an FS-CDMA technique, a transmission rate is controlled according to communication channel environment, spread code groups are repeatedly selected in a receiving side so as to obtain a frequency diversity gain. Accordingly, it is possible to reduce interference between users. In addition, even in a case where strong interference induced from electronic exists, it is possible to implement low-power, stable human-body communication and to ensure a communication quality.
