Abstract

In this paper, we propose a novel method suitable for unequal error protection(UEP) and unequal recovery time (URT) properties, namely the Duplicating-Expanding Window Fountain(D-EWF) codes. We implement duplicating windows and expanding windows techniques to improve the performance of both more important bits (MIB) and less important bits (LIB). We analyze the proposed method over binary erasure channels (BEC) by using asymptotic analysis. The D-EWF codes inherit the advantages of both EWF codes and the duplicating windows method. Therefore the UEP property of D-EWF codes is more obvious. Furthermore BER performance of LIB of D-EWF codes converges very fast. Compared with the previous UEP schemes, simulation results show that the D-EWF codes can provide better UEP performance.
