摘要： One embodiment of the invention relates to a network communication device. The network communication device includes a network interface configured to receive an initial data stream. The network communication device also includes an interleaving redundancy encoder that comprises a memory unit arranged in N columns and D rows. The interleaving redundancy encoder is configured to calculate at least one redundancy byte based on a series of equally spaced, non-consecutive bytes in the initial data stream, where a number of bytes between equally spaced bytes is approximately equal to D−1. Other systems and methods are also disclosed.

摘要： One embodiment of the present invention relates to a network device. The network device includes a receiver configured to be coupled to a transmission medium supporting a multi-carrier channel over which data is communicated as symbols in a first communication state according to an initial bit-loading configuration. The receiver is further configured to detect noise that can corrupt the symbols on the multi-carrier channel. In addition, the receiver is configured to, in response to the detected noise, allocate at least part of the multi-carrier channel to a transient robust channel that facilitates adaptive communication. Other methods and devices are also disclosed.

摘要： One embodiment of the invention relates to a method of data processing. In the method, an initial data stream is received. A series of bytes having a total byte length is selected from the initial data stream, the series of bytes having a span in the initial data stream that is greater than the total byte length. At least one redundancy byte is calculated based on the series of bytes. An output data stream is transmitted over a transmission medium, where the output data stream includes the initial data stream with the at least one redundancy byte therein, and where consecutive bytes in the output data stream have an order that corresponds to an order of consecutive bytes in the initial data stream. Other devices and methods are also described.
