An apparatus and method interleaving symbols coded by a turbo encoder in a communication system that uses the turbo encoder for encoding transmission information into coded systematic symbols and at least one parity symbol pair, and maps the coded symbols using a second or higher modulation order before transmission. The loader car is hydraulically powered along the track and includes a hydraulic rotatable and pivotal segmented boom for releasably collecting debris, utilizing various implements as stored in the implement car. The five input terminals are respectively coupled to a reference voltage, a first voltage source, a second voltage source, an output terminal of the first charge circuit, and an output terminal of the second charge circuit. Furthermore, in some embodiments, an operating state of the portable electronic device can be resolved based in part on the connection state of the portable electronic device. One path is selected based on the determined characteristic and the IO request is transmitted to the adaptor in the selected path. A controller controls a front end clamp openingclosing device to open the front end clamps and controls a pair of rollers to feed a plate held on a plate carry-in path.
