摘要： Provided is a T-DMB receiver and receiving method using a human body as an antenna. The T-DMB receiver includes: an electrode making contact with a human body; a low frequency amplifier receiving via the electrode a current flowing through the human body due to a DMB broadcasting signal emitted by a terrestrial relay station and amplifying the received current; and an impedance matching circuit located between the electrode and the low frequency amplifier and matching an impedance of the human body with an impedance of the low frequency amplifier. Accordingly, a T-DMB receiver easy to carry without a separate antenna can be implemented.

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 is a communication apparatus having a human body contact sensing function and a method thereof. The communication apparatus includes: an electrode that comes in contact with the human body; a contact sensor that is connected to the electrode, and instructs the central processing unit to perform an initial operation if contact with the human body is sensed; and a data processing unit that receives a control signal from the central processing unit so as to select whether to transmit or receive data, and performs a transmitting or receiving operation according to the control signal. Accordingly, in order to reduce power consumption when in a stand-by state before human body contact is made in a communication apparatus using a human body as a communication medium, a human body contact sensor is included so as to minimize power consumption of a micro processing unit and a transmitter/receiver circuit until contact occurs. Therefore, since power consumption is minimized when in a stand-by mode by using a contact sensor having significantly low power consumption, there is an advantage in that a stand-by time of a portable device is extended.

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.
