In order to generate the parity check matrix you must first have the generator matrix and the codeword to check and see if it is correct. 1. Place your generator in row reduction form 2. Get the basis vectors 3. Put the vectors together to get the parity check matrix 4. Check it b multiplying the codewords by the parity = 0 For an example: 2*4 Generator Matrix [1 0 1 1 0 1 1 0] Rank = 2...therefore the number of columns is 2...Rank + X = # of columns of the Generator matrix v1+v3+v4 = 0 v2+v3 = 0 v1 = -r1-r2 v2 = -r1 v3 = r1 v4 = r2 Parity = [-1 -1 -1 0 1 0 0 1]
The single parity check uses one redundant bit for the whole data unit. In a two dimensional parity check, original data bits are organized in a table of rows and columns. The parity bit is then calculated for each column and each row.
Longitudinal parity, sometime it is also called longitudinal redundancy check or horizontal parity, tries to solve the main weakness of simple parity.The first step of this parity scheme involves grouping individual character together in a block, as fig given below 1.1fig.Each character (also called a row) in the block has its own parity bit. In addition, after a certain number of character are sent, a row of parity bits, or a block character check, is also sent. Each parity bit in this last row is a parity check for all the bits in the Colum above it. If one bit is altered in the Row 1, the parity bit at the end of row 1 signals an error. If two bits in Row 1 are flipped, the Row 1 parity check will not signal error, but two Colum parity checks will signal errors. By this way how longitudinal parity is able to detect more errors than simple parity.
Simple parity check
assume that u have received a code, you multiply it to parity check matrix and it results to syndrome, the syndrome identify you the error code from table look up which can be made by multiplying any probable error pattern in generator matrix.
hash validation check,Parity check,check digit
I suppose you mean factoring the polynomial. You can check by multiplying the factors - the result should be the original polynomial.
polyNOMIAL or polyNOMINAL. Nomial in Bulgarian means nothing. Pls. check and ask the question again.
It is one of the type of parity checking methods. when the binary digits are formated as like the binary tree .Then calculate the parity from the root to each leaf node from left to right.
There are none check spelling.
A bit, added to every 8 bits, as a basic data integrity check. The value of this 9th. bit is either chosen so that the total number of 1's is even (even parity) or odd (odd parity).A bit, added to every 8 bits, as a basic data integrity check.

write a programe to build a sparse matrix as an array. write function to check if the sparse matrix is a square, diagonal,lower triangular, upper triangular or tridiagonal matrix

First we find transpose of a matrix and then compare it with the original matrix. For a symmetric matrix A^T = A.Step 1 - Accepts a square matrix as inputStep 2 - Create a transpose of a matrix and store it in an arrayStep 3 - Check if input matrix is equal to its transpose or not If it is equal, then the input square matrix is symmetric.Please find the program attached to find the matrices symmetricity.To find whether a matrix symmetric or not we can use the following code:for(i=0;i

Paribit is a combination of two words; Parity and Bit. In early nineties computing, a check digit or Parity Bit was assigned to a sequence of bits that were to be transmitted over a network. The parity bit was used for security and transmission verification purposes. It either made the entire sequence of bits, even or odd, depending on the checking mechanism being used. Transmissions today use a method called packets and does not employ the check digit method.
We check the weather the number of bits at the input are odd or even and assign the parity bit to 1 or 0. And we do the same to check weather the output is the same as the input. Now as the probability of 2 bits going wrong and we may be confident enough just by checking one bit .
ECC stands for "error correcting code". It is a way to check for accuracy by adding one bit of redundant data (or parity data) to the end of each byte. As an example, when the digits of a byte total an odd number, the parity bit will be a zero. When it is even, it will be a one. If the parity bits do not match their respective bytes, the data is known to be corrupted.
