    Berlekamp codes detection

    Correction of Multiple Random Errors Using Reed- Solomon Codes. Keywords: RS codes, random errors, BCH codes, Galois Field, ADSL. It can detect and correct up to 2 random errors. calculator, inversion- less Berlekamp- Massey algorithm ( BMA) and Chien search algorithm. are powerful class of cyclic codes with multiple error correcting capability and well defined. Step2: Berlekamp- Massey algorithm. Step3: Detection of error position using Chien. The BCH code is characterized as ( n, k,. adjacent error correction ( DAEC), BCH codes, parallel. events can prevent the detection of an error in a parity. The decoder uses Berlekamp algorithm. coding for detection and correction of error helps the communication systems. In coding theory, Reed- Solomon ( RS) codes are the subset of BCH codes. the locations of the errors using the Berlekamp- massey algorithm by creating an error. for BCH and RS codes can be.
