    • A three-dimensional (3D) Trench detector and a method for fabricating the detector are disclosed. The 3D-Trench detector includes a bulk of semiconductor material that has first and second surfaces separated from each other by a bulk thickness, a first electrode in the form of a 3D-Trench, and a second electrode in the form of a 3D column. The first and second electrodes extend into the bulk along the bulk thickness. The first and second electrodes are separated from each other by a predetermined electrode distance, and the first electrode completely surrounds the second electrode along essentially the entire distance that the two electrodes extend into the bulk such that the two electrodes are substantially concentric to each other. The fabrication method includes doping a first narrow and deep region around the periphery of the bulk to form the first electrode, and doping a second narrow and deep region in the center of the bulk to form the second electrode.

    • The present invention relates to an apparatus and method for estimating a channel in a MIMO wireless telecommunication system supporting the 0FDM/0FDMA. The present invention, in estimating a channel by using two or more pilots included in at least one received signal among received signals of a first channel and a second channel received through a first receiving antenna and received signals of a third channel and a fourth channel received through a second receiving antenna, determines a subchannel mapping rule respectively for the received signals of the first channel to the fourth channel, and estimates a channel with a different method according to the determined subchannel mapping rule. That is, the channel is estimated by using two or more pilots included in two or more tiles corresponding to the same subcarrier respectively, in case a subchannel rotation does not exist in the subchannel mapping rule, while the channel is estimated by using two pilots included in an individual tile, in case a subchannel rotation exists in the subchannel mapping rule.
    • 本发明涉及一种用于估计支持OFDM / 0FDMA的MIMO无线电信系统中的信道的装置和方法。 本发明在通过使用包括在第一信道的接收信号和通过第一接收天线接收的第二信道的接收信号中的至少一个接收信号中包括的两个或多个导频和接收到的第三信道和第四信道的接收信号来估计信道 通过第二接收天线,分别确定第一信道到第四信道的接收信号的子信道映射规则,并且根据确定的子信道映射规则来估计具有不同方法的信道。 也就是说,在子信道映射规则中不存在子信道旋转的情况下,通过使用分别对应于相同子载波的两个或更多个瓦片中包括的两个或更多个导频来估计信道,而通过使用包括的两个导频来估计信道 在单个瓦片中,以防在子通道映射规则中存在子通道旋转。
