Abstract

Performance of medium length LDPC codes is directly proportional to error floor .In these codes, error floor can be mainly improved through elimination of short cycles. Hence, for effective elimination of short cycles, it is customary to use a girth conditioning in random construction process. Various accurate techniques, such as, density evolution and EXIT chart are developed for performance prediction of large block length, iteratively decoded LDPC codes. However, for medium block length, this method evolved with erroneous results. Even though, the medium block length LDPC codes have many application, short cycles degrades the performance and adds computational complexity in decoding process.
