Abstract: In one embodiment, the apparatus includes at least one memory configured to store instructions; and at least one processor configured to execute the instructions and cause the apparatus to perform, receiving, by a receiver in an Optical Line Terminal, OLT, a burst of an upstream signal transmitted in burst mode, adjusting settings for an analog signal conditioning of the received upstream signal; performing the analog signal conditioning of the received upstream signal based on the adjusted settings such that a first compensated signal is provided, obtaining coefficient(s) for a digital signal conditioning of the first compensated signal; performing the digital signal conditioning of the first compensated signal based on the obtained coefficient(s) such that a second compensated signal is provided.

Abstract: Apparatus and method for low density parity check code decoding in a first processing device, wherein the method includes receiving a first bit-word of a first length related to a log-likelihood ratio of a bit of a signal; obtaining a second bit-word of a second length that is shorter than the first length, wherein obtaining the second bit-word comprises applying a correction to the first bit-word; and determining a message depending on a set of second bit-words, wherein the set of second bit-words includes the second bit-word.

Abstract: According to example embodiments, the OLT includes at least one processor and at least one memory including computer program code, the at least one memory and computer program code configured to, with the at least one processor, cause the OLT to perform grouping data units for the ONUs in groups, wherein a group includes data units for a subset of the ONUs, encoding the groups of data units into respective sets of at least one codeword, interleaving the at least one codeword of the respective sets thereby obtaining a stream of codewords, and sequentially transmitting the stream of codewords to the ONUs.
