Abstract: The present invention relates to a method and an apparatus for generating and recovering a multiple-access signal in a mobile communication system. In order to generate the multiple-access signal according to the present invention, each transmitter transmits information by using all or a portion of given channel resources. At this time, a signal from each transmitter is mapped to an OFDM time-frequency resource space by a trellis modulation path. The mobile communication system according to the present invention allows the trellis modulation path of the plural transmitters to be mapped to the same resource space. According to the present invention, a receiver uses a symbol-by-symbol message passing method and a path linking method in order to effectively detect and discriminate the signals transmitted from the plural transmitters via the same channel resource space. The receiver, for more efficiently recovering the detected signals, uses a state space extending method, a reverse pre-decoding method and a successive interference cancelation method.

Abstract: An embodiment of the present invention relates to a method for enabling a transmission terminal to execute a pairing process in device to device communications makes a feature of comprising: a step of classifying a plurality of link ID for dividing data transceiving channel into a part group of one or more link IDs; a step of selecting an available candidate link ID part group among the part groups of the link IDs; a step of selecting the available candidate link ID part group among the part group of the link ID; a step of transmitting the pairing request message including the candidate link ID part group information; and a step of receiving a pairing response message corresponding to the pairing request message. According to the embodiment, the method has a good point which does not have large overhead for searching the connection ID when the number of the terminals is small at the assignment of the connection ID in the device to device communication environment. Therefore, the overlapping probability of the connection ID between the terminals is reduced even if the number of the terminals is increased in a specific range. The method has an effect capable of providing the smooth communication between the device and the device.

Abstract: PURPOSE: An apparatus and a method for adjusting transmission power in a UWB communication system are provided to ensure the quality of a transmission signal. CONSTITUTION: If transmission power change request is received from at least one receiving node, an adaptive power adjustment unit(415) adjusts the length of a transmission pulse for each reception node to correspond to the transmission power value provided form the reception node.

A PPM(Pulse Position Modulation) modulator(405) performs the PPM for encoded data. A pulse generator(410) outputs the transmission signal by multiplying a transmission pulse by the output signal of the PPM modulator according to a selected time hopping code.
