摘要： In a multi-carrier system, the carriers (f 0 ... f 511 , f 512 ... f 1023 , ..., f 3584 ... f 4095 ) are grouped in subsets (SUBSET1; SUBSET2; ...; SUBSET8). A constellation information transmitting arrangement (BiGi_TA), for instance located in the multi-carrier receiver (RX), produces for each carrier subset (SUBSET1; SUBSET2; ...; SUBSET8) a limited set of parameter values (B1, G1; B2, G2; ...; B8, G8) and transmits these sets of parameter values (B1, G1; B2, G2; ...; B8, G8) to a constellation information receiving arrangement (BiGi_RA), for instance located in the multi-carrier transmitter (TX). Through interpolation of the limited set of parameter values (B1, G1; B2, G2; ...; B8, G8) the latter constellation information receiving arrangement (BiGi_RA) determines the constellation where each carrier (f 0 ... f 511 , f 512 ... f 1023 , ..., f 3584 ... f 4095 ) of a carrier subset (SUBSET1; SUBSET2; ...; SUBSET8) will be modulated with.

摘要： In a single-carrier or multi-carrier modulator (MOD), data symbols are modulated on at least one carrier in accordance with at least one constellation scheme. Idle data symbols are replaced by null data symbols and the latter null data symbols are associated with a low power constellation point of the at least one constellation scheme. The constellation points associated with the data symbols are randomly transformed into constellation points of equal power. In this way, idle data symbols are transferred with minimised power and sufficiently randomised to allow equaliser training and/or tracking at the receiving demodulator (DMOD) and to avoid high crest factors in multi-carrier systems.

摘要： A triangular interleaver (INTERLEAVER) contains a triangular shaped matrix (MAT) of memory cells, each row of which constitutes a first-in-first-out queue. To increase or decrease the interleave depth of the interleaver (INTERLEAVER), the number of interleaved data bytes read from each row of the matrix (MAT) is positively or negatively linearly related to the ordinate number (0, 1, 2, 3, 4) of this row. In this way, impulse noise immunity of transmission of the outgoing interleaved data stream (OID) over a transmission line (TL) is kept substantially independent from transmit rate changes.

摘要： In a multi-carrier communication system wherein data are transferred bi-directionally in a time division duplexed way, a first pilot carrier is used to transfer a sample rate between two transceivers (VDSL_LT, VDSL_NT) and a second pilot carrier is used to transfer a time division duplexing frame rate between the two transceivers (VDSL_LT, VDSL_NT). The first pilot carrier has an instantaneous frequency that is a fraction of the sample rate of the first transceiver (VDSL_LT) and is orthogonal to other carriers used in the multi-carrier communication system. The second pilot carrier has a mean frequency that is a fraction of the time division duplexing frame rate and is also orthogonal to the other carriers used in the multi-carrier communication system. The second pilot carrier is different from the first pilot carrier.
