Controlling Over-Optimism in Time-Warp Via CPU-Based Flow Control
In standard optimistic parallel event simulation, no restriction exists on the maximum lag in simulation time between the fastest and slowest logical processes (LPs). Overoptimist...

Near-Optimal Sublinear Time Algorithms for Ulam Distance
We give near-tight bounds for estimating the edit distance between two non-repetitive strings (Ulam distance) with constant approximation, in sub-linear time. For two strings of l...

Real-Time R-D Optimized Frame-Skipping Transcoder for Low Bit Rate Video Transmission
For the low bit rate (LBR) video communications, LBR transcoding is performed by the transcoder to match the network bandwidth and the performance of the client. One of typical tr...

Low-Complexity Optimal Detection for Hybrid Space-Time Block Coding and Spatial Multiplexing
— The combination of space-time block codes (STBC) and spatial multiplexing (SM) schemes has the advantages of diversity gain and high data rate. For such STBC/SM hybrid systems,...
