摘要： A method of adjusting equalization parameters in a receiver wherein a bit error rate (BER) in a data stream is measured from the number of corrected bits in data blocks which have an information section and an error correction section. A predetermined equalization parameter is changed, and the bit error rate (BER) after change is again measured to find out how to change the predetermined equalization parameter until an optimum is reached.When adjusting the threshold value of the receiver, the history of occurring bits preceding the actual sampled bit is taken into consideration in that the amount and direction of adjustment is derived from a look-up table.

摘要： A method for correcting the phase of a clock in a data receiver which receives a data flow representing different signal levels with logical high and low signal values and signal transitions positioned therebetween, wherein the positions of such signal transitions between respective two adjacent logical signal values are evaluated for correcting the phase of the clock. The position of a signal transition between a first pair of signal values on one level (11) or a second pair of signal values on the other level (00) is weighted stronger in the evaluation then the positions of signal transitions between adjacent single signal values (1,0) of different signal levels.

摘要： A decision feedback structure for recovering a bit stream out of received signals is disclosed, wherein the sampling instant may be tuned in dependence of the sequence or pattern of the preceding bits so as to follow the bit sequence dependent instant of the maximum eye opening. The decision-feedback equalizer structure includes decision means for making a bit value decision at a sampling instant, a feedback path to feed back bit values to said decision means and means for adapting the sampling instant for a bit value decision made by said decision means with respect to the sampling phase depending on the bit values of preceding bits, in particular depending on the bit value of the previous bit.

摘要： A method of signal equalization of a transmitted bit stream by means of a feed forward equalizer is provided, whereby the signal is decomposed into at least two components and the components are multiplied with equalization parameters to form equalized components, which are superposed to form an equalized signal, and whereby conditional bit error rates by counting faulty transmitted bits in dependence of preceding and succeeding bits are determined and the equalization parameters are tuned dependent on the determined conditional bit error rates.

摘要： A method for selecting an optimum delay length in a polarization mode dispersion (PMD) compensator configured with a constant-length delay line and deployed in an optical communication system. The optimum delay length depends on the data modulation format, bit rate, and/or signal bandwidth and is preferably selected such that outage probability in the communication system is at a minimum. System performance of a PMD compensator configured with a constant-length delay line having the optimum length approaches that of a PMD compensator configured with a variable-length delay line. The method extends the application range of constant-length delay line PMD compensators while reducing the cost of implementing high-performance PMD compensation.

摘要： The present invention provides a high capacity switching system for use in a transport network, which contains a number of input/output subsystems and a central interconnection means configurably interconnecting the input/output subsystems. The subsystems have input/output line modules for receiving and transmitting data signals to and from transmission lines of the network, one or more link modules connecting the subsystems to the interconnection means, and local switching means switching data signals in time and space domain between the input/output modules and the one or more link modules within one subsystems. The link modules are adapted to aggregate data signals from different input/output line modules of the same input/output subsystems and destined to input/output line modules of another one of said input/output subsystems into signal bursts and add a payload gap to each signal burst. The switching system further has a scheduler which configures the interconnection means during the payload gaps to switch the signal bursts to their destination subsystems.

摘要： The delay setting of an optical delay line interferometer (DLI) used to decode differentially encoded phase shift keyed signals (DPSK or DQPSK) is controlled using a control signal representative of the ratio Perr2/Perr1 of the rate of occurrence of double errors and the rate of occurrence of errors. The ratio Perr2/Perr1, as the delay setting of the DLI is varied, exhibits a characteristic W-shaped structure consisting of a local maximum at the optimum value and two minima adjacent to the maximum, one on each side of it. This structure is present over a wide range of signal to noise ratio and residual dispersion.
