Abstract: A method for communication includes receiving first data timed by a first clock and receiving a signal including second data timed by a second clock, which is independent of the first clock, and generating a stream of data samples corresponding to the second signal. The received first data are resampled responsively to a time-varying phase shift between the first and second clocks to generate resampled data timed by the second clock. The resampled data are applied in estimating and subtracting an alien crosstalk component from the stream of data samples.

Abstract: A ground component is made of a columnar or cylindrical conductor and is connected to a ground potential. A cover component is cylindrical and made of a material containing dielectrics. The cover component is arranged at a distance from the ground component so as to cover the outer surface of the ground component, with the ground component inserted therein. The antenna element is arranged between the inner surface of the cover component and the outer surface of the ground component.

Abstract: A communication apparatus includes a receiver disposed in proximity to a transmitter, and a crosstalk cancellation circuit. The receiver includes an input buffer, a front end, and an adaptive resampling circuit. The input buffer receives from the transmitter aggressor data, the aggressor data being timed by a transmitter clock clocking the transmitter. The front end receives data over a communication link, the data being serialized according to a receiver clock clocking the receiver, the receiver clock operating independently of the transmitter clock. The front end further generates a stream of data samples corresponding to the received data. The adaptive resampling circuit resamples the aggressor data, and generates resampled data timed by the receiver clock. The crosstalk cancellation circuit estimates, based on the resampled data, a crosstalk error signal related to the aggressor data, and subtracts the estimated crosstalk error signal from the stream of data samples.

Abstract: Data symbols in an input signal are detected with a slicer of a DFE of a transceiver device. An output of a feedback filter of the DFE is generated, during a particular clock cycle, based on a first set of one or more data symbols detected during first one or more previous clock cycles and a second set of one or more data symbols detected during second one or more previous clock cycles. The second set is separated from the first set by a third set of one or more data symbols detected during third one or more clock cycles that occur after the first one or more clock cycles and before the second one or more clock cycles, where the output is generated without use of the third set of symbols. The output is subtracted from the input signal to generate an equalized input to the slicer.

Abstract: Systems and methods for performing high-speed multi-channel forward error correction using external DDR SDRAM is provided. According to one exemplary aspect, an interleaver/deinterleaver performs both read and write accesses to the DDR SDRAM that are burst-oriented by hiding active and precharge cycles in order to achieve high data rate operations. The interleaver/deinterleaver accesses data in the DDR SDRAM as read blocks and write blocks. Each block includes two data sequences. Each data sequence further includes a predetermined number of data words to be interleaved/deinterleaved. The PRECHARGE and ACTIVE command for one data sequence is issued when a preceding data sequence is being processed. Data in one read/write data sequence has the same row address within the same bank of the DDR SDRAM.

Abstract: Efficient synchronization techniques that support multiple reference clocks in an EQAM device. Consider a plurality of different modulators in the EQAM device receiving data from a corresponding plurality of different sources having corresponding different timing references (i.e., different source reference clocks). To accommodate this, the modulators all operate using a common system clock, and each modulator is provided with a phase synchronizer. The phase synchronizer synchronizes the modulated symbol phases to the corresponding reference clock.

Abstract: A device and method for canceling or attenuating harmonics noise without distorting the incoming signal. An exemplary device includes the use of an estimation loop to generate an artificial signal to eliminate or attenuate the influence of harmonics. The estimation loop includes a mixer adapted to produce a mixed signal by processing or combining the incoming signal and the artificial signal. The estimation loop includes an error detector, a low-pass filter, a parameter estimator, and a numerically controlled oscillator. The parameter estimator produces information relating to the phase, frequency, and amplitude of an incoming harmonics spur and will be used by the numerically controlled oscillator to generate the artificial signal. If the mixed signal contains relatively low levels of harmonics residuals, the mixed signal is produced at the output in lieu of the incoming signal.
