摘要： Provided are a terminal supporting peer-to-peer (P2P) communication, a communication method using the terminal, and a billing method based on the terminal. A transceiver of the terminal is implemented to support P2P communication with an adjacent terminal in the same cell. Thus, when short-range communication is possible, the terminal performs P2P communication directly with the adjacent terminal, not via a base station. Consequently, when terminals use different mobile telecommunication service providers or there is no base station network, the terminals can be used for short-range communication. When a receiving channel state becomes satisfactory while communication with an adjacent terminal is being performed via a base station, the terminal switches to a P2P communication mode and performs communication with the adjacent terminal. On the contrary, when the receiving channel state deteriorates while communication with the adjacent terminal is being performed in the P2P communication mode, the terminal switches to a base station communication mode and performs communication with the adjacent terminal. Therefore, it is possible to use the terminal for short-range communication without attaching an additional short-range communication module to the terminal.

摘要： Provided is a voltage multiplier converting an alternating current (AC) electromagnetic wave into a direct current (DC) voltage signal in a radio frequency identification (RFID) tag, and including means for obtaining voltage gain, the means being connected to an input terminal through which the AC electromagnetic wave is input. The voltage multiplier can generate a greater DC output voltage than a conventional voltage multiplier at the same input power. Therefore, a desired DC output voltage can be obtained at low input power, so that an effective operating distance can be increased. In addition, since the voltage multiplier is easily integrated into a tag chip using a complementary metal-oxide semiconductor (CMOS) process, the size of the tag does not increase and it is easy to package an antenna and the tag chip.

摘要： Provided is a low-complexity and low-power-consumption turbo decoder with a variable scaling factor. The performance of the turbo decoder is enhanced by evaluating a decoding convergence degree of the turbo decoder using a sign difference ratio (SDR) value, limiting the iterative-decoding number, and calculating and applying a variable scaling factor producing optimal performance in each decoding convergence area based on the SDR value, and power consumption is reduced by reducing the average number of decoding iterations. Thus, the performance degradation when the encoded block is large, which is a shortcoming of a conventional EMLMAP algorithm, can be prevented, the average number of decoding iterations can be reduced, and accordingly power consumption can be reduced.
