摘要： A method of minimizing jitter in a system for rate adapting a data signal for transport through a synchronous network. A phase difference is measured between a data clock synchronous with the data signal and a local clock of the synchronous network. A timing reference (F) indicative of a frequency difference between the asynchronous data signal and the local clock is measured using the measured phase difference. Calculation of the timing reference includes compensating ambiguity in the measured phase difference.

摘要： A method of a conveying data through an optical communications system. An optical signal is received through the optical communication system, the optical signal comprising data symbols and SYNC bursts, each SYNC burst having a predetermined symbol sequence. The received optical signal is oversampled to generate a multi-bit sample stream. The sample stream is partitioned into blocks of contiguous samples, wherein each block of samples partially overlaps at least one other block of samples and encompasses at least one SYNC burst and a plurality of data symbols. Each block of samples is independently processed to detect a value of each data symbol.

摘要： A system and method for detecting digital symbols carried in a received optical signal. The system comprises a functional element operative to receive a stream of samples of an electrical signal derived from the received optical signal and to evaluate a non-linear function of each received sample, thereby to produce a stream of processed samples. The system also comprises a detector operative to render decisions about individual symbols present in the received optical signal on the basis of the stream of processed samples. In an embodiment, the non-linear function computes substantially the square root of each received sample.

摘要： A method of recovering a clock signal from an optical signal received through an optical communications system. A digital sample stream is processed to generate a dispersion compensated signal. The dispersion compensated signal is then tapped to obtain upper side band and lower side band signals of each received polarization of the optical signal. The upper side band and lower side band signals are then processed to compensate polarization dependent impairments, and the clock recovered from the resulting optimized.

摘要： A base station communicates, with a mobile station, data associated with a packet-switched session in which the mobile station is involved. In response to a handover request from the mobile station, the base station accesses information provisioned for the mobile station to determine whether the mobile station is to be subjected to mobility restriction. Based on the accessed information, the base station determines whether to allow handover of the mobile station. A message is sent to the mobile station to indicate that the requested handover is not allowed if the base station determines that the requested handover is not allowed.

摘要： A method and system for averaging the effects of polarization distortions across a multitude of transmitted data streams in a dual polarization multiplexed optical communications system. Data streams are interleaved amongst each other in accordance with a predetermined pattern. The interleaved data streams are symbol mapped and modulated to provide a pair of optical signals. The pair of optical signals are orthogonally polarized, and multiplexed for transmission across an optical fiber. A receiver circuit receives the transmitted signal and extracts the interleaved data streams. The interleaved data streams are de-interleaved to generate the original data streams. While the data streams can be interleaved and transmitted via a single wavelength optical signal, the data streams can be interleaved and transmitted over two or more different wavelength optical signals to further mitigate the effects of polarization distortions.
