摘要： An active hybrid circuit for a full duplex channel generates a duplicated voltage at the current output stage to reduce the energy of the transmitter transmitted to the receiver. The active hybrid circuit cancels the energy of the transmitter transmitted to the receiver when it is operated in a full duplex channel with high-speed transmission. The active hybrid circuit for full a duplex channel comprises a transmit digital-to-analog converter for generating an analog transmit signal, a receive analog-to-digital converter for receiving an analog receive signal, a duplicated voltage digital-to-analog converter for generating a corresponding duplicated voltage according to the analog transmit signal of the transmit digital-to-analog converter, and a plurality of signal combiners for subtracting the duplicated voltage from the analog transmit signal to cancel the influence of analog transmit signal to the analog receive signal.

摘要： A data transmission device is applied to a network apparatus having an automatic crossover function, and is connected to a transmission control unit, such that the transmission control unit detects an operating status of the network apparatus and accordingly generates a control command. Thereby, a current source generating unit provides current sources to a first-mode converting unit and a second-mode converting unit according to the control command. This allows a suitable data transmission processing mode to be selected automatically and instantaneously for the operating status of the network apparatus by the current sources from the current source generating unit and the control command generated from the transmission control unit, so as to achieve power saving, low distortion and/or anti-interference.

摘要： Timing recovery method and device for combining pre-filtering and feed-forward equalizer functions are proposed and used in a digital communication system. A signal receiver is provided to receive a signal transmitted from a signal transmitter in the communication system, and recovers a sampling clock phase of the received signal to the phase of the signal transmitted from the signal transmitter. The method is used to control the signal receiver to transform the received signal to a signal similar to a Nyquist pulse after the pre-filtering and feed-forward equalizing operations are performed on the received signal, thereby improving the performance of the following sampling timing recovery process and increasing the signal noise ratio (SNR) of the received signal.

摘要： A receiver with baseline wander compensation is applicable to a digital communication system. The receiver includes an Analog-to-Digital Converter (ADC), a slicer, a threshold value detector, a gain controller, a baseline wander compensator, a delay circuit, an analog gain stage, and a digital gain stage. The baseline wander compensator is used to perform an operation and a filtering process on a voltage obtained prior to processing by the slicer and a voltage after the processing so as to obtain a baseline wander voltage value for compensation and control. The threshold value detector and the gain controller dynamically produce control signals of analog gain and digital gain. The analog gain stage compensates degrading of communication signals passing through transmission channels in an analog gain manner. The delay circuit is used to compensate the delay of the conversion performed by the ADC. The digital gain stage compensates insufficiency of the analog gain.

摘要： A data processing system and method are provided. A first combination logical encoding unit encodes a first set of encryption data to create digital symbols and outputs the digital symbols to an analog/digital symbol processing unit. Further, a combination logical decoding unit performs logical operations to transform a first set of multi-dimensional digital symbols converted from multi-dimensional analog symbols received from a network via the analog/digital symbol processing unit to create a second set of encryption data. Then, the analog/digital symbol processing unit outputs the second encryption data to a second combination logical encoding unit where the second set of encryption data is encoded to create a second set of multi-dimensional digital symbols. A comparing unit then compares the first and second sets of multi-dimensional digital symbols to determine the validity of the first set. The data processing system and method of the present invention reduces the cost on hardware implementation of a data transmitting/receiving interface for data processing and transformation, especially on the implementation of a storage unit.

摘要： This invention presents a novel receiver architecture for full-duplex multi-level PAM systems. The receiver employs an Analog-to-Digital Converter (ADC) that has a sample rate flexibly specified as (Ns+1)/Ns baud rate where Ns is an integer equal or greater than 1. A fractional-spaced echo canceller is used to cancel the echo at the ADC output. The use of a fractional sampling rate higher than the baud rate also enables the timing recovery function be implemented in the digital domain and hence eliminates the need of using the complex analog phase selection circuit. The receiver is also capable of fast, blind start-up by use of a decision feedback equalizer with unity main tap and a soft level slicer. The timing phase can be optimally located using a derivative channel estimator. Once the “eye-open” condition is achieved, the channel equalization is switched to the use of linear equalizer coupled with an error feedback equalizer to alleviate the error propagation problem associated with the decision feedback equalizer.
