Irregular turbo codes and unequal error protection

Turbo codes (TC) with unequal error protection (UEP) are introduced. We consider a serial cascade of an array of repetition codes, an interleaver, and a TC. Such a coding scheme was introduced by B.J. Frey and D.J.C. MacKay (1999) as an irregular turbo code (ITC). A lower bound on the protection level of the ITC is presented. Additionally, simulation results are shown.
