Algorithm for single error correction using H codes
Algorithm for single error correction using H codes
(OP)
I have been able to generate an algorithm to randomise a bit position where an error is likely to occur.Which basically generating an algorithm to select different bit positions of the transmitted codeword for different integer values obtainable from the algorithm.This scheme is employed in the single bit error correction and single bit error detection.
I am currently faced with a problem of randomly selecting any two different bit positions in such a way that every bit position is selected for different integer value obtainable from the algorithm
I urgently need help on this.Thx

PS: Watch out for flakey Random routines. Personally, I'd let it run for a while and make a histogram to confirm that it's hitting all the values.

Tharsmission speed? max. tolerable delay ?

As regards the origin the data...i am not too particular about that.I would like for us to assume a 4 bit binary data.

Normally, for a 4 bit data implementing SECSED we would be using the 7,4 matrix which is of the form
1110100
1101010
1011001
The above code of of hamming distance 3.Now,the problem i am facing is constructing a code with hamming distance 4 for implementing SECDED?

program to encode different ECC-s and detect the error
It is easy to add more polynomials. Presently it has only
three 32th order and one of each 16,48 and 56th
order polynomials.
