摘要： The present invention relates to a communication system and method for transmitting sync flags and pilot symbols during sync symbol periods. Example embodiments provide a method for sharing sync symbols to communicate flag sequences and pilot sequences during a sequence of sync symbol periods. The method includes modulating the pilot sequence by multiplying a pilot code by each value of the pilot sequence, and modulating the flag sequence by multiplying a flag code by each value of the flag sequence. The pilot and flag codes are mutually orthogonal to each other and each includes at least two non-zero values. The method further includes generating a resulting sync symbol sequence based on the modulated pilot sequence and modulated flag sequence, and sending the resulting sync symbol sequence during the sync symbol period.

摘要： An access node is configured to control crosstalk between an activating channel associated with a first terminal and active channels associated with respective other terminals. The access node detects a control signal sent by the first terminal over the activating channel in a designated phase of an initialization process of the first terminal, determines an error signal from the detected control signal, correlates the error signal with one or more corresponding signals sent by respective ones of the other terminals over the active channels, estimates crosstalk from the active channels into the activating channel based on the correlation, and configures a vectoring signal processing module to control the estimated crosstalk. The control signal sent by the first terminal comprises a value selected by the first terminal from a set of two or more values and prior to its detection the particular selected value is unknown to the access node.

摘要： Data words are converted to codewords in accordance with a run-length limited (RLL) or maximum transition run (MTR) code in which the codewords are subject to one or more constraints on the number of consecutive like symbols. The data words and codewords are each partitioned into a number of disjoint subsets. Associated with each of the disjoint subsets of data words is a distinct mapping. A given data word is converted to a codeword by applying to the given data word the mapping associated with the subset containing that data word. The mappings are configured to utilize symmetry whenever possible. For example, if Y=&psgr;(X) represents the mapping of a given data word X onto a corresponding codeword Y. then it is preferred that X′ and Y′ representing the words X and Y in reversed order, satisfy the relation Y′=&psgr;(X′). An example of an efficient high-rate, multi-purpose code in accordance with the invention is a rate 16/17 code satisfying (0,15,9,9) RLL and (0,3,2,2) MTR constraints. This exemplary code can be further processed using interleaving techniques to generate other higher rate codes.
摘要翻译：数据字根据游程长度受限（RLL）或最大转移运行（MTR）代码转换为码字，其中码字受连续相似符号数量的一个或多个约束。数据字和码字被分成多个不相交的子集。与数据字的每个不相交的子集相关联是一个不同的映射。通过将给定的数据字应用到与包含该数据字的子集相关联的映射，将给定的数据字转换成码字。映射被配置为尽可能地利用对称性。例如，如果Y = psi（X）表示给定数据字X到对应的码字Y的映射，则优选地，以相反的顺序表示字X和Y的X'和Y'满足关系Y' = psi（X'）。根据本发明的有效的高速率，多用途代码的示例是满足（0,15,9,9）RLL和（0,3,2,2）MTR约束的速率16/17代码。可以使用交错技术来进一步处理该示例性代码以生成其他较高速率代码。

摘要： In a passive optical network, an upstream transmission rate from an ONT to an OLT can be optimized by matching a transmission scheme for a channel to the upstream transmission characteristics of the channel. An FEC coding can be made channel dependent so that channels with low error rates can use minimal protection, and therefore minimal overhead, while channels with high input bit error rates can use the level of FEC coding required to produce a desired output bit error rate.
