摘要： A method and apparatus for a control bus for connection of electronic devices. An embodiment of a method includes coupling a transmitting device to a receiving device, including connecting a control bus between the transmitting device and the receiving device, with the control bus being a bi-directional, single-line bus. The method further includes obtaining control of the control bus for either the transmitting device or the receiving device, with the device obtaining control becoming an initiator and the other device becoming a follower. One or more control signals are converted to one or more data packets, with each of the one or more control signals representing one of multiple different types of control signals. The generated data packets are transmitted from the initiator to the follower via the control bus.

摘要： A method for converting source data to a channel-modulated signal having a plurality of pairs of in-phase (I) and quadrature-phase (Q) data in a mobile station, wherein the mobile station uses at least one channel, includes the steps of: a) encoding the source data to generate at least one data part and a control part; b) generating at least one spreading code to be allocated to the channel, wherein each spreading code is selected on the basis of a data rate of the data part and the control part and spreading codes are selected so that two consecutive pairs of the I and Q data are correspondent to two points located on same point or symmetrical with respect to a zero point on a phase domain; and c) spreading the control part and the data part by using the spreading code, to thereby generate the channel-modulated signal. The method is capable of improving a power efficiency of a mobile station by reducing a peak-to-average power ratio in a mobile communication system.

摘要： A method and an apparatus to recover a high frequency component of an MP3 encoded audio signal in an audio decoder. The method includes: generating a filter bank value of a low frequency band from a modified discrete cosine transform (MDCT) coefficient, which is extracted from an input bitstream according to a window type, extracting transient information of a frame according to the window type and selecting a weight coefficient according to the extracted transient information, recovering a filter bank value of a lost high frequency band from the generated filter bank value of the low frequency band, and adjusting the recovered filter bank value of recovered high frequency components according to the weight coefficient.
