The PAPR of CAMC is very low since the amplitude has a constant value, which is accomplished at the cost of redundant bits for the precoding in CAMC. We show, however, that redundant bits in CAMC can be reconfigured into parity bits in a single parity check product code (SPCPC). An ...

In a two-dimensional parity-check code, the information bits are organized in a matrix consisting of rows and columns. For each row and each column, one parity-check bit is calculated. As a result, the last column consists of check bits for all rows and the bottom row consists of check...
A method uses an outer code that is a concatenation of code words generated by a parity check encoder. The outer code word is permuted by an interleaver. The high rate coding provides good performance with a simple structure. An odd parity check bit is generated for each data word of recei...
PURPOSE: An apparatus and method for coding an LPDC(Low Density Parity Check) code are provided to perform real time processing, facilitate extension of a code, simplify a device and easily obtain an inverse matrix in case of decoding. CONSTITUTION: An internal column address generator(801) outp...

Codeforece : 1360C. Similar Pairs(水题) https://codeforces.com/contest/1360/problem/C We call two numbers xx and yysimilarif they have the same parity (the same remainder when divided by 22), or if |x−y|=1|x−y|=1. For example, in each of the pairs (2,6)(2,6), (4,...
⚖️ Drop-in parity with Flake8, isort, and Black 📦 Built-in caching, to avoid re-analyzing unchanged files 🔧 Fix support, for automatic error correction (e.g., automatically remove unused imports) 📏 Over 800 built-in rules, with native re-implementations of popular Flake8 plugin...
This paper proposes a novel quasi-cyclic low-density parity-check convolutional code, and a two-stage construction algorithm with modified progressive edge growth (PEG) method is provided. We propose both encoder and decoder implementation architecture for this code. The quasi-cyclic form provides the...
The inclusion of 7 bits tends to be used in some RS485 where the extra bit is used for a global message. With the above mods, the form represents: The next several commands require a bit more explanation in my opinion. They are the Stop bit, Parity and Handshaking. The Handshaking prop...
