bch and reed-solomon decoder simulation

simulation of binary and non-binary bch decoder

Description

simulation of binary bch decoding algorithm for bch(n, k) with t bits error correction capability.
three steps:
syndrome generation + inverse-free Berlekamp-Massey algorithm + chien search algorithm
simplifie = 1 sets the simplified version of Berlekamp-Massey algorithm, which takes t cycles while normal BMA takes 2t cycles.

simulation for non-binary bch (reed-solomon) decoding algorithm RS(n, k):
3 steps: syndrome+BMA+chien

for both simulation, n, k and t can be changed according to the size and correction ability of the code

• Required Products: Communications System Toolbox
• MATLAB release: MATLAB 7.0.1 (R14SP1)

How to modify the source code so that the detected errors can be corrected?

Thanks. Its good.

Thank you very much for posting this.It is really very helpful to implement bch decoder in hardware.I am new to matlab.So please tell me how to change the syndrome values?

Thanks in advance

Could you add some comments on it? especially it is a bit hard to understand the [imba] part.
ps. anybody know what does 'imba' stand for there? I know it must be a stupid question. Does it mean "IMplementing Berlekamp-massey Algorithm "?

damn it , why can't I watch this file
