This paper proposes an efficient scalable coding scheme with fine-grain scalability, where the base layer is encoded with H.26L, and the enhancement layer is encoded with PFGS coding. Motion compensation with adaptive block size has greatly contributed to the coding efficiency improvement in H.26L. In order to improve efficiency of the enhancement layer coding, an improved motion estimation sch...
Network coding (NC) has been regarded as a promising technology for throughput improvement in wireless networks, so a thorough understanding on the possible throughput gain from using NC is essential for the application of such technology. Available studies of throughput gain from NC, which mainly focus on only coding sub-layer or both MAC layer and coding sub-layer but largely neglect the prim...
one of the most important goals for increasing recognition and treatment revenue is transmitting vital data to medical care team, more quickly. nowadays, use of new technologies for transmitting data will deploy more and more daily. in this article, for transmitting electrocardiogram, first we code the signal into a suite of codes, then we will use bluetooth technology to transmit data from off...
This paper proposes a principled extension of the traditional single-layer flat sparse coding scheme, where a two-layer coding scheme is derived based on theoretical analysis of nonlinear functional approximation that extends recent results for local coordinate coding. The two-layer approach can be easily generalized to deeper structures in a hierarchical multiple-layer manner. Empirically, it ...
Network coding refers to a scheme where a node is allowed to generate output data by mixing (i.e., computing certain functions of) its received data. The unique characteristics of wireless medium renders network coding particularly useful. For instance, network coding can be used to achieve the minimum energy-per-bit for multicasting in a wireless ad hoc network. In addition to optimizing energ...
