摘要： A super-frame for transmission in an optical communications system comprises two or more data frames and a parity frame. All frames in the super-frame have been encoded in accordance with a first Forward Error Correction (FEC) scheme. The parity frame is computed over the two or more data frames (prior to or concurrently with or after encoding via the first FEC scheme) according to a second FEC scheme. At a receiver, the super-frame is decoded in accordance with the first FEC scheme to generate a set of FEC decoded frames in which residual errors are clustered, that is, are non-Poisson. The second FEC scheme, which is particularly suited or designed to correct the clustered non-Poisson residual errors, is used to correct the residual errors.

摘要翻译：用于光通信系统中传输的超帧包括两个或多个数据帧和奇偶校验帧。超帧中的所有帧已经根据第一前向纠错（FEC）方案被编码。根据第二FEC方案，在两个或更多数据帧（在通过第一FEC方案编码之前或之后同时或之后）计算奇偶校验帧。在接收机处，根据第一FEC方案对超帧进行解码，以生成一组FEC解码帧，其中残留错误被聚集，即非泊松。特别适用于或设计用于校正聚类非泊松残差的第二FEC方案用于校正残余误差。

摘要： A method of forward error correction in an optical communications system. A signal to be transmitted is logically defined as a super-frame comprising a plurality of frames including a parity frame and a predetermined set of data frames. Each frame of the super-frame is processed in accordance with a first FEC scheme having a known error correlation characteristic. At least the set of data frames is processed in accordance with a second FEC scheme which is selected based on the error correlation characteristic of the first FEC scheme.

摘要： A method and system for predicting channel fading, particularly in a mobile wireless environment, that is accurate for long-range predictions. The method comprises estimating a model parameters based on a current channel estimate, and recursively adapting the model parameters to predict future channel fading coefficients until a predetermined re-acquisition condition is satisfied. Once the re-acquisition condition has been satisfied, the model parameters are again estimated based on a current channel estimate. The acquired model parameters are adaptively updated and used in a Kalman filter.
