Design of Rate-Compatible Protograph LDPC Codes

The most common way to generate a rate-compatible family of codes is puncturing. In this method, one starts with a low-rate mother code and then selectively discards some of the coded bits to arrive at higher-rate codes. This approach is simple, but is not free of problems. Specifically, the mother...
