  • Patent number: 8249040
    Abstract: In a transmission device and method for a CDMA communication system, when a shorter frame message is generated during transmission of a longer frame message, the transmission of the longer frame message is interrupted, whereupon the shorter frame message is immediately transmitted in place of a portion of the longer frame message. In one embodiment, after the longer frame message is interrupted and the shorter frame message is transmitted, only the tail portion of the longer frame message is transmitted thereafter. That is, the replaced portion of the longer frame message is not transmitted following the shorter frame message transmission. In an alternative embodiment, following the shorter frame message transmission, the remainder of the longer frame message, from the point of interruption, is transmitted in its entirety. In the latter case, the longer frame message is delayed by the length of the shorter frame message.

  • Publication number: 20120081682
    Abstract: According to an example embodiment, a method to determine an exposure start position and orientation includes loading a substrate on a moving table. The substrate includes at least one alignment mark of a first set of alignment marks of a first pattern layer patterned thereon. At least one alignment mark of a second set of alignment marks of a second pattern layer is exposed on the substrate using maskless lithography. A position of the at least one alignment mark of the first set of alignment marks and a position of the at least one alignment mark of the second set of alignment marks on the substrate is measured. A relative orientation difference between a desired exposure start orientation and an obtained exposure start orientation is acquired using the measured positions of the at least one alignment mark of the first set of alignment marks and the at least one alignment mark of the second set of alignment marks.

  • Patent number: 7797617
    Abstract: Provided is an interleaving method that can reduce error occurring during transmission at a receiving end in an Orthogonal Frequency Division Multiplexing (OFDM) system. According to the interleaving method, transmitted data bits are recorded in an interleaving memory; and the stored data bits are read based on a predetermined sequence to perform symbol interleaving, tone interleaving and cyclic shift simultaneously. Also, to simplify the logic of the OFDM system, the data bits transmitted from an interleaver go through Fast Fourier Transform (FFT) mapping, and the FFT mapped data bits are modulated. In short, the logic can be simplified by performing FFT mapping followed by modulation.
