To be presented at ISIT 2005, Adelaide, Australie.
We investigate a new class of codes which is in some senses a hybrid between
LDPC codes and turbo-codes.
We show that when the parameters of this
class are well
chosen they display very good iterative decoding
performances and have
at the same time
a minimum distance which is typically linear in the code length.
