Abstract: A transceiver architectures can contain an encoder and a decoder for communicating high speed transmissions. The encoder can modulate signal data for being mapped in a constellation that is generated based on concatenations of an E8 lattice having binary and non-binary codes. The data can be transmitted at a high speed according to the constellation with an embedded E8 lattice configuration in order to generate a coding gain. A decoder operates to decode the received input signal data with a decreased latency or a minimal latency with a high spectral efficiency.

Abstract: Multi-reliability regenerating (MRR) erasure codes are disclosed. The erasure codes can be used to encode and regenerate data. In particular, the regenerating erasure codes can be used to encode data included in at least one of two or more data messages to satisfy respective reliability requirements for the data. Encoded portions of data from one data message can be mixed with encoded or unencoded portions of data from a second data message and stored at a distributed storage system. This approach can be used to improve efficiency and performance of data storage and recovery in the event of failures of one or more nodes of a distributed storage system.

Abstract: The present disclosure provides a method and a device for transmitting data using a LDPC code. The method for transmitting data using a LDPC code includes: determining a check code length according to a current LDPC code rate; informing a receiving end about the current LDPC code rate and the check code length, adding a check code with the check code length to data to be sent, and implementing a LDPC encoding using the current LDPC code rate, so as to obtain LDPC code data; and sending the LDPC code data to a receiving end. The method and the device of the present disclosure can improve spectrum effectiveness of transmitting data using LDPC code.

Abstract: A manner of processing data for transmission in a data communication network. A node having a main memory and an interleaver is provided. Received data is stored in the main memory and a bandwidth map is prepared. The data is then selectively read out and pre-processed according to the bandwidth map and stored in an interleaver memory. The data is later read out and post-processed before interleaving into a downstream data frame. The pre- and post-processing provide the data in a more efficient form for interleaving.
