20140369213 | METHOD FOR ESTIMATING CHANNEL BASED ON IEEE 802.11 ad WITH LOW COMPLEXITY - Exemplary embodiments of the present invention relate to a method of estimating a channel in a wireless communication network using the IEEE 802.11ad communication standard, and more particularly, to a method of estimating a channel which can determine a channel environment and actively select a channel estimation scheme according to the determined channel environment, and correctly estimate the channel while reducing the amount of computation by selectively using a pilot channel estimation value only in a pilot estimation period and adjacent pilot estimation periods when the channel changes severely, i.e., when a deep hole occurs, in the pilot estimation period although an LTF channel estimation value is used. | 12-18-2014 |
20140024760 | THREE-DIMENSIONAL NANOFIBER SCAFFOLD FOR TISSUE REPAIR AND PREPARATION METHOD THEREOF - The present invention provides a three-dimensional nanofibrous scaffold for tissue regeneration, which is increased in porosity and thickness to enlarge the surface area thereof, thereby enabling cell adhesion at a high density, and a method for fabricating the same. The method for fabricating a three-dimensional nanofibrous scaffold for tissue regeneration includes the steps of: (a) preparing a polymer solution; (b) preparing a nanofiber matrix, in which a plurality of nanofibers is entangled with each other, from the polymer solution prepared in step (a) using electrospinning; and (c) immersing the prepared nanofiber matrix in a solution and subjecting the solution to ultrasonication, thereby increasing the thickness and porosity of the nanofiber matrix. According to the inventive scaffold fabricating method, the nanofiber matrix prepared by using electrospinning is ultrasonicated in a solution, so that a three-dimensional nanofibrous scaffold with improved thickness and porosity can be provided in a simple and low-cost manner. | 01-23-2014 |
