摘要： For synchronisation purposes, a transmitter (TX) multiplexes a pilot carrier with carriers whereon data elements (DATA) are modulated, and transmits the pilot carrier together with the modulated carriers to a receiver (RX). The immunity of the pilot carrier for interferers, such as radio amateur signals, is improved by modulating the pilot carrier with a non-constant signal, for instance a random signal, an alternating signal or even scrambled data elements (DATA), before transmission thereof. Since demodulation of the pilot carrier in the receiver (RX) and averageing successive demodulated pilot carriers reduces the effect of the interference induced on the non-constantly modulated pilot carrier, the degradation of the synchronisation between transmitter (TX) and receiver (RX) is reduced significantly.

摘要： A windowing unit (WFU) improves band-limited noise immunity of a fourier transformer (FT) of which it is a part. The windowing unit (WFU) comprises a digital window filter (WI) and a folding processor (F). The window function (W) of the digital window filter (WI) consists of a window head (HEAD), a window body (BODY), and a window tail (TAIL), and the shape of the window function (W) is chosen so that the window head (HEAD) is complementary to a tail (BODY TAIL) of a window body (BODY), and similarly the window tail (TAIL) is complementary to a head (BODY HEAD) of the window body (BODY). The folding processor (F) performs the task of mapping the information received in the window head (HEAD) on to the tail (BODY TAIL) of the window body (BODY) and mapping the information received in the window tail (TAIL) on to the head (BODY HEAD) of the window body (BODY).

摘要： A modulator/demodulator (MODEM) is equipped with a rotation circuit (TROT) in its transmitting part (TP) and a rotation circuit (RROT) in its receiving part (RP). To compensate for clock speed differences between the clocks of two communicating modems, the receive rotation circuit (RROT) of one of them rotates the phase of received data carriers in proportion to their respective frequencies. Furthermore, to align transmit data symbols with received data symbols, the transmit rotation circuit (TROT) of one of the modems rotates the phase of the transmit data symbols. Thereto, the phase rotation applied to each carrier whereon the transmit data symbols are modulated, is proportional to the frequency of this carrier and to a phase difference measured between a received pilot carrier (PT) and an expected received pilot carrier (PT.sub.-- E). When the rotation to be applied to a transmit data symbol corresponds to a time shift of half the length of one sample, a sample is duplicated or deleted in a transmit data symbol by transmit skip/stuff circuit (TSS).

摘要： Communication link bonding apparatus and methods are disclosed. Multiple communication links are configured, at a communication link termination module which transfers communication traffic between a further communication link and the multiple communication links, as a group for providing an aggregate group communication traffic rate. The aggregate group communication traffic rate is allocated among the grouped communication links, and communication traffic is distributed for transmission on the communication links in accordance with the communication traffic rate allocation. Once communication links of a group have been initialized using respective initialization communication traffic rates, a communication traffic rate allocation for each of the communication links may be calculated based on an attainable communication traffic rate of the communication link.

摘要： To allocate a number of data elements to a set of carriers, the carriers are divided into N subsets of carriers according to a predetermined carrier criterion whilst the data elements are classified into N groups of data elements according to a predetermined data criterion, N being an integer greater than one. The predetermined data and carrier criterion have a relation on the basis of which the N subsets of carriers are associated one by one to the N groups of data elements. The data elements classified in such a group are then allowed to be modulated only on carriers which form part of the subset associated with this group. In addition, for each subset of carriers and related group of data elements, the distribution is obtained by means of information from subset dependent `required SNR (Signal to Noise Ratio) per data element`-tables and previously carried out SNR measurements for each carrier.

摘要： To negotiate a data rate for future transmission over a communication link (TL), a first transceiver (TRX1) proposes a limited number of data rate values to a second transceiver (TRX2). During the selection phase wherein the first transceiver (TRX1) and the second transceiver (TRX2) at the other end of the communication link (TL) have to select one of the data rate values, one of the transceivers (TRX1, TRX2) may decide that none of the proposed data rate values is likely to be used for future transmission. This transceiver then announces a new proposal whereupon a new set of adapted data rate values is produced by one of the transceivers and proposed to the other.

摘要： A method for interleaving data frames, a forward error correcting device and a modulator including such a device, wherein each data frame to be interleaved is divided into a plurality of words, each containing the same amount of data bytes. An overhead extension is added to the words and additionally, the resulting codewords are applied to an interleave buffer (IB) to be written in matrix-shaped structure of memory cells included in the interleave buffer (IB). This matrix-shaped structure is filled column by column in such a way that each codeword occupies another column. Data bytes are read out of the matrix-shaped structure row by row, as a result of which the data frames are interleaved.
