Abstract: Using midambles, tracking delay profile creator 107 opens correlation windows in the range of 8 chips before and behind the top path and creates delay profiles within this range. From the delay profiles, path determiner 108 detects whether or not there is a new path before the top path, and, when there is a new path, determines whether or not this is its path. Based on the result of the determination at path determiner 108, when the new path is its path, frame position controller 109 sets the top path with the new path. On the other hand, when the new path is not its path, the top path set earlier is retained as is as the top path. Then, in accordance with the timing of the top path set, a received signal is demodulated. By this means, reception quality can be improved.

Abstract: A sheet feeding apparatus includes a stacking tray for stacking a sheet, a sheet feeding device for feeding the sheet, a register device for aligning a leading edge of the sheet fed by the sheet feeding device, a recognition device for recognizing a state that the sheets stacked on the stacking tray have different widths, and a setting device for setting a feeding distance according to a result of the recognition device. A control device controls the sheet feeding device to feed the sheet for the feeding distance.
