摘要： A CAN module (200) comprising a bit duration compensation component (240) arranged to generate a compensated transmit command signal for controlling the driver component (250) to drive a dominant state on the CAN bus (230). The compensated transmit command signal (245) comprises dominant bits of a compensated-bit duration T bit_ cp = T bit_ Tx + tc, wherein tc comprises a compensation offset derived at least partly from a difference between a transmit-bit duration of a digital transmit command signal (212) and a receive-bit duration of a received data signal (214).

摘要： The disclosure provides a method for implementing an optical label, including that: an optical network is domain-partitioned according to Reconfigurable Optical Add-Drop Multiplexer (ROADM) nodes, and one or more frequencies of label signal are allocated for each domain; in each domain, an allocated frequency of label signal is circulated among ROADM nodes and/or among carriers within an ROADM node according to a preset time-division rule; a label signal is sent on a carrier or an optical channel using a circulated frequency of label signal. The disclosure further provides a system for implementing optical label. With the solution of the disclosure, label-signal transmission may be implemented on more carriers or optical channels with less frequencies of label signal, thereby not only reducing demand of the system for the number of label frequencies, but also facilitate label-signal extraction.

摘要： One embodiment relates to a method of driving a transmission signal with pre-emphasis having minimal voltage jitter. A digital data signal is received, and a pre-emphasis signal is generated. The pre-emphasis signal may be a phase shifted and scaled version of the digital data signal. An output signal is generated by adding the pre-emphasis signal to the digital data signal within a driver switch circuit while low-pass filtering is applied to current sources of the driver switch circuit. Other embodiments, aspects, and features are also disclosed.

摘要： A base station uses the initial tap coefficient set according to an adaptive algorithm so that a communication terminal may omit the procedures preceding the determination of the initial value by the adaptive algorithm. As a result, the communication terminal can reduce equalization load and thus the time required for equalization.

摘要： An encoder which encodes a voice in accordance with LD-CELP (low delay code excitation linear prediction encoding) of the ITU-T Recommendation G.728 as a method wherein, when a vibration wave such as a voice signal is encoded by vector quantization, the code is secretly combined with another data. The encoder stores dividing key data kidx by which 128 types of representative vector data (waveform codes) yj; j = 0, 1, ..., 127 are labeled with 0 or 1 in the order from the uppermost bit. If the bit to be combined is "0", the vectors are quantized by using only the waveform codes yj corresponding to the bit "0" of the dividing key data kidx as the selection objects. If the bit to be combined is "1", the vectors are quantized by using only the waveform codes yj corresponding to the bit "1" of the dividing key data kidx as the selection objects. Thus, the outputted voice code is combined with another datum bit.

摘要： A method for slicing a received signal includes the steps of receiving a signal (5) representing one of a constellation of ideal data points (1-9, ) in a planar signal space, the received signal being at a point (42) in the signal space, and assigning to the received signal a decision point (21,26, 25, 27, ) having a predetermined magnitude (|A|) and an angle (?) representing a corresponding ideal signal point (1-9, ). A slicer (30) includes a source (10) for receiving a signal representing one of a constellation of ideal data points (1-9, ) in a planar signal space, the received signal being at a point (42) in the signal space, and circuitry (30), coupled to the signal source (10), for generating a signal (15)representing a decision point (21,26, 25, 27, ) having a predetermined magnitude (|A|) and an angle (?) representing an ideal signal point corresponding to the signal point .
