摘要： A method for determining at least one operational transmit power Snk over a communication channel (Ln) coupled to a disturbance causing transceiver (n) for at least one tone (k), comprises the steps of provision of at least one reference victim communication channel (Lref) for representing at least one reference victim for all victim communication channels which are degraded by cross-talk interferences by said communication channel (Ln), and maximizing the data rate (Rref) over said at least one reference victim communication channel (Lref) under the constraint that the data rate over said communication channel (Ln) achieves a target rate (Rntarget) without exceeding a power constraint (Pnmax).

摘要： A power control method for transceiver units conveying data over discrete tones. The method includes the steps of: determining a transmit power over a physical channel for each individual tone, such that this transmit power maximizes a weighted function of data rates achievable with this tone over the physical channel and over modeled neighboring channels, with the constraint that this transmit power conforms to a transmit power mask, summing up the data rates over the whole set of tones, adjusting the weights such that the total data rates over the modeled neighboring channels reach some target data rates, and such that the total data rate over the physical channel is maximized, with the constraint that each weight is identical over the whole set of tones.

摘要： A multicarrier receiver which receives a cyclically extended multicarrier symbol which is in a serial format is provided. The multicarrier receiver includes a serial to parallel converter, a window which decreases spectral side lobes of the multicarrier symbol and outputs a windowed multicarrier symbol, a difference term generating unit which generates difference terms from the multicarrier symbol in parallel format, a first Fourier transformer which fast Fourier transforms a single carrier of the windowed multicarrier symbol for all carriers of the windowed multicarrier symbol and outputs a first Fourier transformed carrier, a second Fourier transformer which fast Fourier transforms difference terms, and a per-carrier frequency domain equalizer which equalizes all frequencies by deriving necessary fast Fourier transforms utilizing linear combinations of the first fast Fourier transformed carrier, one or more non-windowed fast Fourier transformed carriers from the second Fourier transformer and the difference terms.

摘要： A multicarrier receiver (RX′) comprises the cascade connection of a sliding Fourier transformer (SLIDING FFT) which subsequently Fourier transforms parts of an incoming cyclically extended multicarrier symbol (MS), and a per-carrier frequency domain equaliser (PC-FEQ) including for each carrier a tapped delay line (TD1, TD2, . . . , TDN/2) for equalising the Fourier transformed parts of the incoming multicarrier symbol (MS). The per-carrier frequency domain equaliser (PC-FEQ) allows to optimise the system capacity individually per carrier, and in a preferred embodiment of the invention includes tapped delay lines (TD1, TD2, . . . , TDN/2) with adaptive complex taps, with an adaptive length and with an individual delay that may differ for different carriers.

摘要： A receiver is disclosed at the head-end or a centralizing unit side in a communications system or network for signals in the upstream direction which is the direction from user to head-end or a centralizing unit that is linked to a number of users, the number being equal to or larger than one. The receiver is suited for the reception of burst mode signals. The receiver performs a channel estimation on a per-burst basis in real time or essentially immediate. The channel estimation is necessary to do successful data detection of modulated data. The receiver of the invention performs the channel estimation and data detection in one compact all-digital mechanism that has no tuning parts. The reception method works in an aspect according to the principle of a matched filter receiver, but stores no local copy of the required matched waveform. Rather, a copy of the matched waveform is included in the preamble of the signals.
