Dear all
I am working on a ldpc encoder project for the dvbs2 spec
I have done the matlab coding for normal frame and rate ½
Now I want to change it to work for short frame and rate ½
Can anyone tell me what to change in this code
The attached file contain two folders one for the working normal frame code and one for the worng code of the short frame
For the normal frame you can fint the file final_encoder_tarek.m
It is the encoding code
The change I tried is to replace the values of normal frame rat ½
By the short frame rat ½
And the added value 90 for every parity bit with 25
What else should be changed I guiss the 360 will remain and it will be 8100 for parity bits and 8100 for info bits
