Abstract: Methods, circuitries, and systems for transmitting data upstream between a first device and a second device and downstream between the second device and the first device are disclosed. A method includes determining an upstream crosstalk effect for an upstream channel and determining a downstream crosstalk effect for a downstream channel. The crosstalk effect includes near end crosstalk from a third device that is non-co-located with respect to the first device and the second device. A data rate of an upstream transmission or downstream transmission is adjusted based on the upstream crosstalk effect and the downstream crosstalk effect.

Abstract: Examples relate to a Forward Error Correction (FEC) encoder, an FEC decoder, Passive Optical Network (PON) systems, an Optical Line Terminal (OLT), an Optical Networking Unit (ONU), and to corresponding methods and computer programs. A forward-error-correction (FEC) encoder that is suitable for generating FEC data for use with hard-decision input at a receiver and for use with soft-decision input at the receiver is configured to generate the FEC data based on payload bits using a Low-Density Parity-Check (LDPC) code. The generated FEC data is generated using a single LDPC code that is suitable for use with soft-decision input and hard-decision input at the receiver or using one of two LDPC codes that are suitable for soft-decision input and hard-decision input, respectively.

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.
