With the coming of the Computer Age and the proliferation of transmissions (particularly digital transmission) came the need for protocols to identify errors.Richard Hammingwas a pioneer inerror detection and correction. Here, at Omni Calculator, we have already covered many of his works: check out...
This makes them attractive in applications where the data unit to be encoded varies in length. In this paper we discuss the parallelization of encoders for low-density parity-check convolutional code. We then present results to show how this parallelism impacts on the area and throughput of ...
a parity bit is a simple form of error detection used in digital communications, computing, and data storage. it is an extra bit added to a binary code to ensure the accuracy of data transmission or storage. the value of the parity bit is determined based on the number of ones (or ...
If QCA consolidates as a possible CMOS substitute, this study can impact the design of future components that uses Gray-code and parity generator, such as embedded digital communications systems that will benefit from the low-power consumption of the QCA technology....
In a communication system, information data bits are encoded in a preset coding scheme when the information data bits are input, and a Low Density Parity Check (LDPC) codeword is generated. The LDPC codeword is interleaved according to a preset channel-interleaving rule. A channel-interleaved ...

In this paper, we propose a design rule of rate-compatible punctured multi-edge type low-density parity-check (MET-LDPC) code ensembles with degree-one variable nodes for the information reconciliation (IR) of continuous-variable quantum key distribution
The parity-check matrix H has a relation with code data C as shown in Equation 1. H*CT=0 [Equation 1] where code data C includes information data S and parity data P, that is, C=[S P]. Various LDPC coding methods have been suggested to calculate the parity data P. ...
The present disclosure relates generally to a low density parity check (LDPC) code that is used to correct errors occurring over a wireless channel, and, more particularly, to an LDPC code that is applicable to a digital broadcasting system. ...
