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.

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.
摘要翻译：提供了一种支持对等（P2P）通信的终端，使用终端的通信方法以及基于终端的计费方法。终端的收发机被实现为支持与相同小区中的相邻终端的P2P通信。因此，当短距离通信成为可能时，终端不直接通过基站直接与相邻终端进行P2P通信。因此，当终端使用不同的移动电信服务提供商或者没有基站网络时，终端可以用于短距离通信。当通过基站进行与相邻终端的通信时，当接收信道状态满意时，终端切换到P2P通信模式，并与相邻终端进行通信。相反，当在P2P通信模式中正在执行与相邻终端的通信时，当接收信道状态恶化时，终端切换到基站通信模式并与相邻终端进行通信。因此，可以使终端进行短距离通信，而不需要向终端附加附加的短距离通信模块。
