Abstract: A decoder circuit that supports non-linear precoded signals is disclosed. The decoder circuit comprises a modulo estimation circuit configured to receive a non-linear pre-coded quadrature amplitude modulated (QAM) data symbol and determine a modulo shift estimate associated with the received QAM data symbol, wherein the modulo shift estimate comprises a modulo shift that brings the received QAM symbol within the predetermined QAM constellation. The decoder circuit further comprises a QAM decoder circuit configured to map the received QAM data symbol to a winning constellation point, wherein the winning constellation point comprises a constellation point in an extended QAM constellation associated with the predetermined QAM constellation, and determine a quantized constellation point comprising a constellation point within the predetermined QAM constellation from the winning constellation point, based on applying the modulo shift corresponding to the modulo shift estimate to the winning constellation point.

Abstract: A system for redistributing bandwidth among a plurality of customer premises equipments (CPEs), wherein each of the plurality of CPEs have an initial bandwidth allocation, comprises a distribution point unit (DPU). The DPU is configured to detect an excess available bandwidth condition of one of the plurality of CPEs, detect a need for additional bandwidth condition of another one of the plurality of CPEs, communicate a bandwidth re-allocation request and a set of granted tones to the CPE having the detected excess available bandwidth condition and to the CPE having the detected additional bandwidth condition, and communicate a time instant at which the set of granted tones should be switched from the CPE having the detected excess available bandwidth condition to the CPE having the detected additional bandwidth condition.

Abstract: An optical network receiver (ONU) circuit associated with a passive optical network (PON) is disclosed. The ONU circuit comprises one or more processors is configured to operate in a hunt state, wherein the one or more processors is configured to detect frame boundaries associated with an incoming data signal based on a detecting a predefined synchronization (psync) pattern associated with the incoming data signal and transition to a pre-sync state, when the predefined psync pattern is detected correctly. The one or more processors is further configured to operate in the pre-sync state, wherein the one or more processors is configured to perform forward error correction (FEC) decoding for the incoming data signal, in order to determine signal statistics associated with the incoming data signal.

Abstract: Examples relate to a transmit apparatus, a receive apparatus, a method for transmitting, a method for receiving and computer readable storage media for transmitting and/or receiving in a communication network. A transmit apparatus for transmitting discontinuous time-frequency operation, DTFO, signals in a communication network comprises a transmitter configured to transmit a DTFO signal comprising monitoring symbols and regular DTFO symbols in the communication network. The apparatus further comprises processing circuitry, which is coupled to the transmitter and configured to generate at least one monitoring symbol for transmission by the transmitter if a time gap of the DTFO signal between two sub-sequent regular DTFO symbols exceeds a first time threshold, wherein the at least one monitoring symbol is configured to enable frequency-domain equalizer, FEQ, adjustment at a receiver of the DTFO signal; and generate a training sequence for transmission by the transmitter if a time period between a last transmission of a monitoring or regular DTFO symbol and a sub-sequent transmission of a DTFO symbol exceeds a second time threshold, the training sequence comprising at least one monitoring symbol preceding a regular DTFO symbol.

Abstract: A system for a digital subscriber line (DSL) network with a DSL interface can operate with processing circuitry that can generate symbols in multicarrier communications with codewords for modulation of a parity check. The codewords can be aligned with symbol boundaries of the symbols in a continuous transmission of the multi-carrier communications. The processing circuitry reduces a number of parity bits by puncturing and a number of data bits for shortening of the codewords so that a codeword boundary is aligned with a symbol boundary for one or more symbols, or a transmission frame of symbols.

Abstract: A method that accomplishes margin equalization utilizing tone ordering is provided. The method includes measuring a respective signal-to-noise-ratio (SNR) margin for each respective tone in a multicarrier channel. A plurality of tone groups is determined by, for each tone group, grouping at least one tone with a relatively high SNR margin with at least one tone with a relatively low SNR margin to form a tone group. Ordering information describing the plurality of tone groups is communicated to a transmitter. The transmitter is configured to load bits for transmission by way of the tones based at least on the ordering information.
