摘要： The present invention concerns adjustment of tap coefficients of a Tomlinson-Harashima precoder in a digital communications path during a data transmission state. According to the invention, the tap coefficients of the Tomlinson-Harashima precoder are adjusted based on content values of a delay line of the Tomlinson-Harashima precoder and on an error variable associated with a receive. Synchronization between the error value and the content values of the delay line is performed according to line frame synchronization information.

摘要： The invention relates to a method for implementing adaptive Tomlinson-Harashima precoding using a digital data communications link, According to the method, the outgoing bit stream is coded into symbols, channel distortion is corrected by precoding (TML) the symbols, the precoded symbols are sent over a data communications channel (2, CHN), in which case the symbols, which have passed through the channel (2, CHN) and signal processing means of the receiver are reconstructed to form a bit stream. According to the invention, updated precoder coefficient parameter values are formed with the aid of an error variable (e), which is dependent on the symbol decisions (S′) of the receiver, the output signal of a decision-feedback equalizer, and a signal (Q) that is formed from the received signal by compensating the effect of the precoder transfer function of the received signal with an inverse precoder transfer function.

摘要： The objective of the invention is to devise a method for establishing a subscriber connection and a system applying the method. According to the method, a digital subscriber connection consisting of a composition of an optical fiber and a metallic pair cable is implemented by transporting a digital information stream in two directions over an optical fiber (2) between a central site and equipment (103) which is connected to the metallic pair cable (4) of each subscriber. According to the invention, the information streams transmitted and received over the pair cables are multiplexed onto the optical fiber by using a multiplexing method of optical signals, whereby the information streams originating from different subscribers are combined onto the fiber by means of passive optical elements and whereby the information streams transmitted from the central site are distributed to each subscriber-specific optical-to-electric conversion element (105) by means of passive optical elements. Thus the multiplexing and demultiplexing need no active multiplexing/demultiplexing electronics common to all subscribers, but rather the active electronics of the conversion elements (105) of each subscriber operates independently without being dependent on the state of operation of other subscriber's conversion elements. Hence the operating power for said electronics can be fed from the respective subscriber through the subscriber's pair cable.

摘要： Method and equipment for creating routing data in packet-switched data communications when the quality-of-service class of the data transfer packet to be routed influences the routing data. Based on protocol data, which can be, for example, an IPv4 destination address, and information of quality-of-service class, auxiliary routing data is defined, which indicates which of the routing data alternatives conforming to this protocol data corresponds to the information of quality-of-class. The routing data is created based on the interaction of the auxiliary routing data and the protocol data. The number of different combinations composed of protocol data and auxiliary routing data appearing in the practical data transfer networks is notably smaller than the number of different combinations composed of protocol data and information of quality-of-service class. This fact is utilized in the solution according to the invention for reducing the amount of required storage capacity.

摘要： The invention relates to a method and apparatus for improving the quality of receiver synchronization on QAM- or CAP-modulated modem connections having an adaptive linear equalizer. The invention is based on the finding that in a QAM- or CAP-modulated data transmission system where the symbol rate and the average carrier frequency are in fixed relationship with each other, the vector formed by the In-phase and the Quadrature component of the detector input signal rotates with the timing phase shift of the receiver. The quality of receiver synchronization is improved by utilizing information extracted from the vector rotation.

摘要： The invention relates to a method and system for implementing a digitally controlled sample and timing clock in a system performing analog and digital signal processing. According to the method, as the timing clock of the digital signal processing is used a clock with a controllable frequency such that said digital signal processing can have a function suited for controlling the frequency of said timing clock, and the conversion of the signal is performed in synchronism with the timing clock of the digital signal processing operation when a delta-sigma converter or a switched-capacitor filter device is employed. According to the invention, the timing and sample clocks are generated by dividing a fixed-frequency clock operating at a frequency substantially higher than that of said timing/sample clock by a digital divider of an integer division factor whose division factor is controlled by means of an at least second-order delta-sigma modulator capable of delivering an output signal of two values so that one of the modulator output signal values selects the division factor to be N while the other value selects the division factor to be N+1, and, further, the delta-sigma modulator controlling the integer-factor divider is adapted to be clocked by the timing signal generated by said integer-factor divider.
