    摘要: Detection apparatus and method for achieving performance close to a Maximum Likelihood (ML) detection having optimal performance and reducing computational complexity in a Multiple-Input Multiple-Output (MIMO) system including a plurality of transmit antennas and receive antennas are provided. The apparatus includes a hard decision part for confirming an initial hard decision value of a receive symbol vector; a candidate symbol selector for selecting candidate symbols restricted to neighbor values of the initial hard decision value; and an interference canceller for canceling interference in the selected candidate symbols and selecting a final candidate symbol from the received symbols using a result of the interference cancellation.

    摘要: An apparatus for adaptively decoding based on a channel variation at a receiver of a communication system supporting an Alamouti mode is provided. The apparatus includes a channel variation estimator for estimating the channel variation; a channel estimator for estimating a channel value of successive channel periods or a channel value of each channel period by comparing the estimated channel variation with a threshold; an Alamouti decoder for decoding a receive signal using an Alamouti method when the estimated channel variation is less than or equal to the threshold; and a Spatial Multiplexing (SM) decoder for decoding the receive signal using an SM method having a square channel matrix when the estimated channel variation is greater than the threshold.

    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.
