Abstract
A new class of rateless codes which are able to provide unequal error protection (UEP) and equal recovery time (ERT) properties is proposed in this paper. Existing UEP-based LT codes have an important property termed unequal recovery time (URT), which means the data with different reliability requirements can be recovered with different overhead, and it is worth noting that the most important bits (MIB) also have better recovery time performance. The proposed codes can recover data with the same overhead and different error performance. We analyze the asymptotic and experimental error performance of the proposed codes, and give the comparison between the proposed and traditional codes, our results show that the new class of UEP rateless codes are useful for scenarios in which the data have different reliability and same timeliness requirements.
