Homomorphic MACs: MAC-Based Integrity for Network Coding
Abstract. Network coding has been shown to improve the capacity and robustness in networks. However, since intermediate nodes modify packets en-route, integrity of data cannot be c...

On the Reversibility of Parallel Insertion, and Its Relation to Comma Codes
This paper studies conditions under which the operation of parallel insertion can be reversed by parallel deletion, i.e., when does the equality (L1 L2) L2 = L1 hold for language...

Optimum Network Coding for Delay Sensitive Applications in WiMAX Unicast
—MAC layer random network coding (MRNC) was proposed in [1] as an alternative to HARQ for reliable data transmission in WiMAX unicast. It has been shown that MRNC achieves a high...

Efficient Placement of Compressed Code for Parallel Decompression
Code compression is important in embedded systems design since it reduces the code size (memory requirement) and thereby improves overall area, power and performance. Existing res...

Video Coding Using Spatially Varying Transform
In this paper, we propose a novel algorithm, named as Spatially Varying Transform (SVT). The basic idea of SVT is that we do not restrict the transform coding inside normal block b...
