    Abstract: A method for digital communication includes generating time-domain symbols (54) having a predetermined symbol duration in accordance with a discrete multi-tone (DMT) modulation scheme. A cyclic extension (56,58) is added to each of the time-domain symbols so as to form data blocks (50,52) having a block length that is not an integer multiple of the symbol duration. A training pattern is generated on one or more tones of the DMT modulation scheme, wherein the training pattern is periodic over a sequence of the data blocks with a period equal to the symbol duration. The sequence of the data blocks is transmitted over a communication channel (26) to a receiver (24), which processes the training pattern so as to determine a response of the channel to the one or more tones.

    Abstract: Methods and systems provide an efficient power save mode for multi carrier modems, such as DMT based ADSL and VDSL modems. Fast transitions from power save mode to full operational mode occur, without the overhead of transmitting large quantities of configuration information between the transmitter and receiver. Signal constellation size changes occurring while operating in power save mode to continue to apply once full operational mode is resumed. Multiple power save modes are enabled, each having a different level of power dissipation and crosstalk, both far end crosstalk and near end crosstalk. Power dissipation and crosstalk can thus be graduated on a line, according to a user-requested bit rate.

    Abstract translation: 方法和系统为多载波调制解调器提供了有效的省电模式,例如基于DMT的ADSL和VDSL调制解调器。 发生从省电模式到完全运行模式的快速转换,无需在发送器和接收器之间传输大量配置信息的开销。 在节电模式下操作时发生信号星座大小变化,一旦恢复完全运行模式,继续施加。 启用多种省电模式,每种模式具有不同的功耗水平和串扰,远端串扰和近端串扰。 因此,根据用户请求的比特率,功率耗散和串扰因此可以在线上分级。

    Abstract: Disclosed is a method, circuit and system for transmission and reconstruction of a video block. A video stream may be composed of sequential video frames, and each video frame may be composed of one or more video blocks including a set of pixels, Prior to transmission of the data associated with a video block, the video block data may be transformed into a set of transform (e.g. frequency) coefficients using a spatial to frequency transform such as a two dimensional discrete cosine transform. Selection of the subset of transform coefficients to be transmitted may be based on a characteristic of the video block.
