    摘要： Modems, methods, and computer program products for falling back to a low speed mode of operation upon detection of abnormal line conditions during startup perform a first phase of a multiphase startup procedure in accordance with a high speed mode of operation. A determination is then made whether the line conditions will support high speed communication. If a high speed connection cannot be established, then subsequent phases of the startup procedure will be performed in accordance with the low speed mode of operation. Otherwise, subsequent phases of the startup procedure will be performed in accordance with the high speed mode of operation. By detecting abnormal line conditions, such as digital discontinuity, severe attenuation, or a local loop having a non-linear frequency response, early in the startup protocol, the remainder of the startup protocol can be performed in accordance with a low speed more of operation as the detected abnormalities in the communication path will prevent the establishment of a higher data rate connection. Accordingly, the reliability and efficiency of the startup protocol are improved.

    摘要翻译： 在启动期间检测到异常线路状况时，回调到低速运行模式的调制解调器，方法和计算机程序产品根据高速运行模式执行多相启动过程的第一阶段。 然后确定线路条件是否将支持高速通信。 如果不能建立高速连接，则根据低速运行模式执行启动过程的后续阶段。 否则，将根据高速运行模式执行启动过程的后续阶段。 通过在启动协议的早期检测到诸如数字不连续性，严重衰减或具有非线性频率响应的本地环路之类的异常线路状况，可以根据较低的运行速度执行启动协议的其余部分 由于检测到的通信路径异常将阻止建立较高的数据速率连接。 因此，提高了启动协议的可靠性和效率。

    摘要： A convolutional encoding/decoding system encodes a data bit stream into n bit parity sets from k bit data bit sets, using code words of length L. The system is dependent upon the finding that unique data to parity tables can be generated where both data and parity bit blocks are w bits in length. The value of w=n(L-k)/(n-k). An encoded parity bit stream is subjected to Exclusive OR operation through a connection mask or masks that are dependent upon the encoding code words. The Exclusive OR operation generates syndrome symbols indicative of the presence of errors in the parity bit stream and which are employed to address a correction table. Parity correction values are derived from the correction table and are used to revise the parity bit stream, which is then decoded, using a parity to data table. A number of parity correction procedures are disclosed.

    摘要： A method and apparatus for identifying an unwanted short message service (SMS) message from SMS messages received by a cellular mobile communication system, which comprises at least a history database (HB) for storing a set (H) of the messages received by the cellular mobile communication system. The method includes the steps of: measuring a difference in an information content between a SMS message (m) received by the cellular mobile communication system and the set (H) of messages stored in the history database (HB), and marking the SMS message (m) as being an unwanted SMS message if the difference that is measured is less than or equal to a predefined threshold value.

    摘要： Method and apparatus for decoding data in a data storage system. In operation, a detector generates an output bit stream in dependence on a data block received from a storage subsystem of the data storage system. A post processor connected to the detector generates a first error corrected bit stream in dependence on the output bit stream and the data block. An error correction decoder connected to the post processor generates a second error corrected bit stream in dependence on the first error corrected bit stream and also generates a checksum in dependence of the second error corrected bit stream. A feedback path supplies from the error correction decoder to the post processor pinning data indicative of locations of correct bits in the second error corrected bit stream in the event that the checksum is indicative of errors in the second error corrected bit stream and the second error corrected bit stream comprises at least one correct interleave. The post processor regenerates the first error corrected bit stream in dependence on the pinning data received from the error correction decoder.

    摘要： Exemplary embodiments of the present invention comprise a method for the use of an intra-disk redundancy storage protection operation for the scrubbing of a disk. The method comprises initiating a disk scrubbing operation upon each disk of a plurality of disks that are comprised within a storage disk array, issuing a disk scrubbing command for a predetermined segment of the disks that are comprised within the storage disk array at a predetermined time interval, and identifying an unrecoverable segment on a disk. The method further comprises determining if unrecoverable sectors comprised within the unrecoverable segment can be reconstructed, and reconstructing the unrecoverable sectors of the unrecoverable segment and relocating the segment to a spare storage location on the disk in the event that the segment cannot be reconstructed within its original storage location.
