Performance for sequential decoding on Rayleigh fading channels has been obtained theoretically and by simulations. Results show that sequential decoding of long constraint length convolutional codes is a good candidate coding scheme for data oriented services in future mobile communication systems. The applicability of such a coding and decoding scheme for(More)
Researchers have proposed the Core Based Trees (CBT) and Protocol Independent Multicasting (PIM) protocols to route multicast data on internetworks. In this paper, we compare the simulated performance of CBT and PIM using the OPNET network simulation tool. Performance metrics include end-to-end delay, network resource usage, join time, the size of the(More)
BACKGROUND Robotic-assisted locomotor training has demonstrated some efficacy in individuals with neurological injury and is slowly gaining clinical acceptance. Both exoskeletal devices, which control individual joint movements, and elliptical devices, which control endpoint trajectories, have been utilized with specific patient populations and are(More)
