Luby transform (LT) codes are often employed during best-effort packet transfers to offer rateless erasure protection. Efficient as they are, these randomized codes with a small number of input symbols often post an inevitable performance trade-off between the decoding failure rates in their waterfall and error-floor regions. In order to surmount this trade-off, we propose a new encoding strategy...
Wireless video streaming often suffers from heavy and varying amount of packet loss. Short-length Luby Transform (SLLT) codes are often employed to offer necessary rateless or universal erasure protection. Nevertheless, a proficient method for finding the optimal degree distributions of SLLT codes is still missing although the asymptotic behaviors of infinite-length LT codes have long been deduced...
Wireless broadcasting of scalable video coded medium grain scalable (SVC/MGS) bit streams requires unequal erasure protection (UEP) at the transport layer in order to ensure graceful degradation of playback video quality over a wide range of frame error rates. Modern wireless broadcasting systems even employ rate less fountain codes to aid the receivers in making inevitable trade¬offs among picture...
Unequal error/erasure protection (UEP) is often employed in multilayer video streaming to ensure successful reception of the important reference layers. In this paper, we investigate possible ways to provide such protection to the multicasting sessions of scalable video codes (SVC) using randomized linear network codes (RLNCs). We surmised that it takes both proper combination of transmitted symbols...
Luby Transform code (LT code) has been a popular and practical technique in the field of channel coding since its proposal. One of the key components of LT code is a degree distribution which is used to determine the relationship between source data and codewords. Luby in his proposal suggested two general methods to construct feasible degree distributions. Such general designs work appropriately...
Luby Transform code (LT code) is the first practical digital fountain code and has been widely used as basic components in many communication applications. The coding behavior of LT code is mainly decided by a probability distribution of codeword degrees. In order to customize a degree distribution for different purposes, multi-objective evolutionary algorithm is introduced to optimize degree distributions...
