摘要： Provided is a carrier recovery apparatus in a vestigial sideband modulation (VSB) type digital television (DTV) receiver. The carrier recovery apparatus dynamically controls a sign determination level which is a reference for determining a sign of an I signal in a sign extractor. Therefore, the carrier recover apparatus can eliminate unnecessary sign extraction caused by zero-crossing which is generated when the receiver receives a pilot signal weaken by a channel ghost, and improves the frequency lock performance in the receiver. Specially, the carrier recover apparatus. can effectively improve the frequency lock performance when comparatively large pattern jitter is existed in a low pass signal caused by a ghost signal produces a long delay time.

摘要： A digital television (DTV) transmitter and a method of processing data in the DTV transmitter/receiver are disclosed. In the DTV transmitter, a pre-processor pre-processes the enhanced data by coding the enhanced data for forward error correction (FEC) and expanding the FEC-coded data. A packet formatter generates one or more groups of enhanced data packets, each enhanced data packet including the pre-processed enhanced data and known data, wherein the data formatter adds burst time information into each group of enhanced data packets. And, a packet multiplexer generates at least one burst of enhanced data by multiplexing the one or more groups of enhanced data packets with at least one main data packet including the main data, each burst of enhanced data including at least one group of enhanced data packets.

摘要： Provided are a semiconductor laser diode and a method of manufacturing the same. The semiconductor laser diode includes a lower cladding layer disposed on a substrate; a ridge including an optical waveguide layer, an active layer, an upper cladding layer, and an ohmic contact layer, which are sequentially stacked on the lower cladding layer, and having a predetermined width, which is obtained by performing a channel etching process on both sides of the ridge; an oxide layer disposed on surfaces of the upper and lower cladding layer to control the width of the ridge; a dielectric layer disposed on left and right channels of the ridge; an upper electrode layer disposed on the entire surface of the resultant structure to enclose the ridge and the dielectric layer; and a lower electrode layer disposed on a bottom surface of the substrate. The method is simpler than a conventional process of manufacturing a semiconductor laser diode. Also, by controlling a wet oxidation time, the width of a ridge can be freely controlled and an ohmic contact layer can be automatically formed.
