摘要: A telecommunication system and related methods. Implementations may include implementations of a method of encoding data for transmission, including forming a frame by encoding a message block using a short-block low density parity check (LDPC) code and an encoder to form a short encoded block, modulating the short encoded block using a modulation format and a modulator to form a modulated short encoded block, including the modulated short encoded block in a data payload of the frame, and transmitting the frame into a telecommunication channel with a transmitter. The frame may be one of a plurality of frames and each modulated short encoded block in each of the plurality of frames may have a constant number of symbols. The frame may include a modulation/code pair (ModCod) including information relating to the modulation format and the short-block LDPC code used for encoding and modulation.

摘要: A data compression system comprising a transmit side having a first receive interface adapted to receive a first quantity of data from a first channel and a compression controller coupled to the first receive interface, a lossless compression controller, and a bandwidth monitor, the lossy compression controller and the bandwidth monitor coupled to a first transmit interface adapted to transmit a compressed first quantity of data into a second telecommunication channel wherein the bandwidth monitor evaluates the bandwidth of the second telecommunication channel and communicates with the compression controller. A decimation controller is adapted to lossy compress a portion of a second data quantity in the first telecommunication channel in response to a lossy compression control signal communicated by the compression controller to form a reduced second data quantity if the compression controller determines, that the bandwidth second transmission channel is insufficient to carry the first data quantity when compressed.

摘要: The current invention involves a forward error detection system, especially for use with Low Density Parity Check codes. A parallel SISO structure allows the decoder to process multiple parity equations at the same time. There is a new SISO decoder which allows for the updating of the Log-likelihood-ratio's in a single operation, as opposed to the two pass traditionally associated with the Tanner Graph's. In the decoder, there is a mapping structure that correctly aligns the stored estimates, the stored differences and the SISO's. There is also the ability to deal with multiple instances of the same data being processed at the same time. This structure manages the updates and the differences in such a manner that all calculations on a single piece of data that are processed in parallel are incorporated correctly in the new updated estimates.
