Low-Latency Error Control of H.264 Using SP-Frames and Streaming Agent Over Wireless Networks
Abstract—A key challenge to low-latency wireless video streaming, where persistent retransmission is impractical, is error control. While SP-frame adaptation of H.264 has potenti...

Lowering Error Floor of LDPC Codes Using a Joint Row-Column Decoding Algorithm
Low-density parity-check codes using the beliefpropagation decoding algorithm tend to exhibit a high error floor in the bit error rate curves, when some problematic graphical stru...

Replication Strategy in Unstructured Peer-to-Peer Systems
1 The unstructured Peer-to-Peer (P2P) systems usually use a “blind search” method to find the requested data object by propagating a query to a number of peers randomly. In or...
