On Array-based LDPC Codes in Channels With Varying Sampling Rate
Lara Dolecek, Venkat Anantharam · UC Berkeley · 2006
We describe a method for enhancing synchronization error correction properties of an array-based LDPC code. The proposed method is based on code expurgation whereby a linear subcode is retained for message encoding and the remaining input bits are used for protection against synchronization errors. The method is easy to implement and incurs a minimal loss in the rate
