Analog-to-digital (A/D) converters are key components in digital signal processing (DSP) systems and are therefore receiving much attention as DSP becomes increasingly prevalent in telephony, audio, video, consumer products, etc. The varying demands on conversion rate, resolution and other characteristics have inspired a large number of competing A/D conversion techniques. Sigma Delta Modulators: Nonlinear Decoding Algorithms and Stability Analysis is concerned with the particular class of A/D techniques called oversampled noise-shaping (ONS) that has recently come into...

In this work, we introduce new path diversity schemes in order to provide robustness for both unicast and multicast video communication applications over wireless ad hoc networks. We first propose a general architecture for multipath video streaming over wireless ad hoc networks. Then for the unicast case, we propose multipath streaming with two node-disjoint paths, which have minimum concurrent Packet Drop Probability (PDP) among all path pairs. This approach minimizes the probability of concurrent loss of all the descriptions, thus optimizing the worst case Multiple Description Coding (MDC)...
