    摘要： An apparatus and a method for canceling interference based on Maximum Likelihood (ML) at a receiver of a multi-antenna system are provided. The method includes estimating a channel using a signal received over one or more receiver antennas; generating one or more weights using the estimated channel to cancel interference; detecting a candidate symbol having the shortest Euclidean distance through Maximum Likelihood using a first weight; and soft-decoding the candidate symbol using a second weight. Therefore, by receiving the signal based on the ML under the interference, the system capacity can be increased and the reception performance can be enhanced.

    摘要： In a method of forming a metal-insulator-metal (MIM) capacitor in a semiconductor device, after forming a capacitor insulation layer on a lower metal layer of the MIM capacitor, an upper electrode is formed by ion implantation into the capacitor insulation layer and silicidation, without a typical reactive ion etching process. Consequently, damage to the capacitor insulation layer can be minimized, and the area of the capacitor need not increase.
