摘要： Disclosed is the system and method to remove noises in voice signals in a voice communication. The at least one embodiment of the present disclosure performs a spectral subtraction (SS) for voice signals based on a gain function by a spectral subtraction apparatus, performs clustering of voice signals consecutive on a frequency axis of a spectrogram for the voice signals in which the spectral subtraction has been already performed to designate one or more clusters, and extracts musical noises by determining continuity of each of the designated clusters on the frequency axis and a time axis of the spectrogram to extract to musical noises.

摘要： A light emitting device includes a metal backing layer, a reflective electrode layer disposed on the metal backing layer, and a plurality of nanorods disposed on the reflective electrode layer. Each nanorod includes a p-semiconductor layer, an active layer, and an n-semiconductor layer, which are sequentially stacked on the reflective electrode layer. The light emitting device further includes an anti-reflection electrode layer disposed on the nanorods, and quantum dots disposed between the nanorods. The method includes sequentially growing the n-semiconductor layer, the active layer, and the p-semiconductor layer on a substrate; forming the nanorods by etching the p-semiconductor layer using a mask pattern; sequentially forming the reflective electrode layer and the metal backing layer on the p-semiconductor layer and then removing the substrate; disposing quantum dots between the nanorods; and forming the anti-reflection electrode layer on the nanorods.
