Abstract: In a system that performs mobile communication using at least two beams, by determining a size of a beam based on information that is acquired for mobile terminals attempting an access, a beam of a form having an adaptive size is formed and thus communication is performed. A beam sector including a plurality of beam segments and a beam segment that forms a beam of a minimum size within entire coverage is set, and while forming one beam per beam sector, a size of a beam is adaptively determined.

Abstract: Disclosed are a method of upsampling based on a maximum-resolution image and red, green and blue (RGB) composition and an apparatus performing the same. An image generating method may include acquiring visible-channel images included in multi-spectrum images, upsampling a remaining image excluding a maximum-resolution image from the visible-channel images, based on the maximum-resolution image among the visible-channel images, and generating an RGB composite image by composing the upsampled remaining image and the maximum-resolution image.

Abstract: A method of forming a beam and a method of allocating a resource in a long term evolution (LTE)-based mobile communication system are provided. More particularly, a method of forming an adaptive satellite multiple beam for enhancing multiple beam performance and a method of allocating a resource that can relieve interference in a beam that is formed according to the method in a multiple beam system in which satellite communication and mobile communication is coupled based on LTE are provided. When providing a communication service that supports both satellite communication and ground communication, performance degradation can be reduced with the same interface, and by providing a method of forming an adaptive beam and a method of allocating a resource by relieving interference of the formed beam in consideration of a position of the terminal by independently allocating a subcarrier to the terminal and enabling the terminal to process the subcarrier, performance of a multiple beam can be improved.
