    摘要： Provided are an apparatus and a method for providing a relay service in a wireless communication system. The apparatus includes a modulator, an encoder, and a transmission unit. The modulator modulates a transmission signal according to a modulation degree. The encoder encodes a modulation symbol provided from the modulator using a convolution code of a ring domain. The transmission unit transmits the signal provided from the encoder to a relay station. The relay station detects a signal where signals received from different transmission ends are added in a real domain, and relays the detected signal, thereby providing a relay service without an additional time resource.

    摘要： Methods and apparatuses are provided for determining an interference transmission mode (TM) at a communication device in a cellular communication system using a resource element (RE) defined by frequency and time. A first signal is received in one RE. The first signal comprises a serving signal and an interference signal. A first vector of the received first signal is projected onto each of N projection vectors. A traffic-to-pilot ratio (TPR) decision metric of the interference signal is determined by using N pairs of an actual squared value and an expected squared value which are corresponding to the projected first vector. A TM of the interference signal is detected by determining a TF of the interference signal which minimizes the TPR decision metric from among predetermined transmit format (TF) candidates.

    摘要： In a method of manufacturing a carbon nanotube, a boat configured to receive substrates is positioned outside of a synthesis space where the carbon nanotube is synthesized. The substrates are loaded into the boat. The boat is then transferred to the synthesis space. A process for forming the carbon nanotube is performed on the substrates in the synthesis space to form the carbon nanotube. Thus, the carbon nanotube may be effectively manufactured.
