    摘要: A method for transmitting scattered pilot signals in a multi-carrier system is disclosed. The method includes: in each time slot, in time dimension, putting each 4 OFDM symbols into a group according to the order of the OFDM symbols; in each group of OFDM symbols, in frequency dimension, selecting, for each OFDM symbol, a plurality of valid sub-carriers to transmit scattered pilots, wherein for a same OFDM symbol, between each 2 valid sub-carriers selected, there are 7 valid sub-carriers; for different OFDM symbols in a same group, the valid sub-carriers selected are interleaving in frequency domain; and transmitting scattered pilot signals on the valid sub-carriers selected. The solution helps the multi-carrier system to handle multi-path channel with large delay spread, to obtain more accurate channel estimation and to achieve better receiving performance.

    摘要: Provided are an apparatus, method, and medium for processing an image. In the apparatus, at least one image selected from images to be stitched so as to make colors of overlapped sections of the images as identical with each other as possible and operating again in response to a re-alignment signal, and an image correction unit generating the re-alignment signal after correcting a color of at least a part of the overlapped sections as a result of the shifting of the at least one image in consideration of colors of the overlapped sections Then the shifting of the image is repeated. Therefore, even when the overlapped sections of the images are not identical in color, the overlapped sections of the images can be precisely aligned when the images are stitched for forming a panoramic image, thereby making the panoramic image more accurate.
