Multi-edge framework for unequal error protecting LT codes
H. V. Beltrão Neto, Werner Henkel, Valdemar C. da Rocha · 2011
A multi-edge framework for unequal error protecting (UEP) LT codes is derived by distinguishing between the edges connected to each protection class. Under the framework introduced, two existing techniques for the design of unequal error protecting LT codes can be evaluated and explained in a unified way. Furthermore, a simple and flexible design technique is proposed for UEP LT codes with good performance.
