Abstract :
We describe a method for enhancing the synchronization error correction properties of an array-based low density parity check (LDPC) code. The proposed method uses code expurgation: a linear subcode is retained for message encoding and additional input bits are used for protection against synchronization errors. The method is easy to implement and incurs minimal loss in rate
