A channel encoding method in a communication or broadcasting system includes identifying an input bit size, determining a block size (Z), determining a low density parity check (LDPC) sequence to perform LDPC encoding, and performing the LDPC encoding based on the LDPC sequence and the block size.

Presented are systems and methods for automatically decoding and demodulating radio signals in a communication network. Embodiments utilize a one-dimensional (1D) convolutional neural network (CNN) as the key architecture of a decoder that utilizes one or more 1D convolution windows to perform convolution operations on to-be-decoded or demodulated input signals received by the communication network. In embodiments, this may be achieved by receiving, at a CNN correlator implemented in a decoder, an input signal that comprises unknown data and applying to the input signal, in the discrete time domain, a convolution to obtain a CNN correlator output to which an activation may be applied to decode the input signal and output the decoded signal.

Improved techniques for recovering from an error condition without requiring a re-transmittal of data across a high-speed data link and for improved power usage are disclosed herein. A data stream is initiated. This stream includes different types of packets. Error correcting code (ECC) is selectively imposed on a control data type packet. A transmitter node and a receiver node are connected via a hard link that has multiple virtual channels. Each virtual channel is associated with a corresponding power-consuming node. When the receiver node receives the control data type packet, error correction is performed if needed without re-transmittal. When a final data type packet is transmitted for each virtual channel, the transmitter node transmits an end condition type packet. A corresponding power-consuming node that corresponds to the respective virtual channel transitions from an active state to a low power state.

A transmission processing method includes: performing encoding or decoding, or instructing a second communication device to perform encoding or decoding. The encoding or decoding uses a multi-level structure.

It is presented a method for modulating data for transmission over a communication channel to a receiver network entity. The method is performed in a transmitter network entity and comprises the step of: modulating data in accordance with a modulation scheme, the modulation scheme comprising a first set of constellation points respectively representing only one bit sequence and a second set of constellation points respectively representing two different bit sequences.

Communication links may include a combination of diverse communication channels, and more preferably one or more low latency (but low bandwidth) communication links and one or more high bandwidth (but high latency) communication links. Advantageously, the use of a plurality of communication links may facilitate transmitting information quickly and reliably.

Described herein is a system and method for coded streaming data to facilitate recovery from failed or slow processor(s). A batch of processing stream data can be partitioned into a plurality of data chunks. Parity chunk(s) for the plurality of data chunks. The plurality of data chunks and the parity chunk(s) can be provided to processors for processing. Processed data of at least some (e.g., one or more) of the plurality of data chunks, and, processed data of parity chunk(s) are received. When it is determined that processed data for a pre-defined quantity of data chunks has not been received by a pre-defined period of time, the processed data for particular data chunk(s) of particular processor(s) from which processed data has not been received are determined based, at least in part, upon the received processed parity chunk(s) and the received processed data chunk(s).
