摘要： Conventional modems coupled in parallel to a coupling need a sharing apparatus, which can be avoided by providing each modem with a detector for detecting upstream/downstream signals to be transceived by other modems coupled in parallel. The detector has a distinguisher for distinguishing upstream signals and downstream signals. An additional filter between the coupling and detector prevents the modem from interfering with the other modems coupled in parallel. The modem may have an active/passive state corresponding with a lower/higher impedance.

摘要： Systems (1) with interleavers (2) for interleaving data units and with de-interleavers (3) for de-interleaving data units, are made more efficient and less complex by storing data units in the form of stacks in the memories (29,39) of said interleavers (2) and said de-interleavers (3), by calculating stack positions for data units to be (de)interleaved, and by adapting stacks through shifting before the interleaving or after the de-interleaving. Such a system (1) does not require more than [(N−1)(D−1)]/2 memory elements, the theoretical memory size for the block length N and the interleaving depth D. Said data units are stored at subsequent positions, with said data units at said subsequent positions being adapted through shifting before the interleaving or after the de-interleaving to further subsequent positions. An interleaver (2) comprises a calculator (21), a shifter (23) and an inserter (24). A de-interleaver (3) comprises a calculator (31), an extracter (34) and a shifter (33).

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 from interference, 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 averaging 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： 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： To transparently transport an incoming clock signal (CLK2) with a known frequency over a network segment wherein transmission between a transmitter (TX) and a receiver (RX) operates synchronous to a transmit clock signal (CLK1) and receiver clock signal (CLK1′) which are synchronized, the transmitter measures the phase difference (P) between the incoming clock signal (CLK2) and a reference signal (R) obtained from the transmit clock signal (CLK1). The measured phase difference (P) is communicated to the receiver (RX) and used therein to generate a copy clock signal (CLK2).
