    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: A method of mitigating transmission delay fluctuations in a communication system having a variable data rate and block-oriented subsystems, such as interleavers. The method comprises interspersing dummy data with genuine data to form a combined data stream for the subsystems. When the data rate decreases, the rate at which dummy data is supplied increases to stabilize the delay. In one embodiment, the dummy data is discarded prior to transmission and may be reintroduced as needed on the receiving end. In another embodiment, the dummy data is transmitted and only discarded after processing at the receiving end. For this later embodiment in a multi-tone system, the dummy data can be sorted onto separate sub-carriers for transmission and the power levels for those carriers can be dropped to reduce overall power consumption and crosstalk. The concept can be used to extend seamless rate adaptation to systems with forward error correction.

    摘要: One embodiment relates to a method of communicating data between a transmitter and a receiver of a communication system. In this method, a payload data stream is received from a network interface layer. The payload data stream includes data units eligible for retransmission and data units non-eligible for retransmission. These data units are grouped into containers, where a container is associated with a container identifier that distinguishes the container from other containers. The containers are grouped into data transmission units, where a data transmission unit includes at least one container along with redundancy information that facilitates error detection for that data transmission unit. The data transmission units are transmitted to the receiver as a transmission data stream. Other methods and systems are also disclosed.

    摘要: A splitter circuit (19) serves to combine on the transmission side signals which are to be transmitted in different frequency bands (A-C), as well as to separate on the reception side these signals which are transmitted in different frequency bands. For this purpose, the splitter circuit (19) has a circuit section (13) designed as purely passive, for the rough signal and impedance separation, as well as the filters (3, 4; 9, 10) allocated to the individual transmission and reception sections, for the exact filtering out of the individual signal in each case. These separate filters (3, 4; 9, 10) are arranged in the transmission direction upstream of a corresponding four-wire/two-wire conversion, and in the reception direction downstream of a corresponding two-wire/four-wire conversion, so that the signal stream takes place via these filters in one direction only, and the filters can be designed as purely active filters or digital filters. In particular, the filters (3, 4; 9, 10) can be dimensioned as of high Ohmic resistance in the reception path, in order to reduce the power consumption.
