Reliability-based hybrid ARQ (RB-HARQ) is a recently developed form of incremental-redundancy ARQ. The RB-HARQ technique can be used with codes that use soft-input, soft-output (SISO) decoders, such as convolutional codes and turbo codes. In RB-HARQ, the bits that are to be retransmitted are adaptively selected at the receiver based on the estimated bit(More)
—We consider the use of selective-retransmission automatic repeat request (ARQ) protocols to improve communication performance on partial-time jamming channels. The schemes that we propose are based on reliability-based hybrid ARQ (RB-HARQ), in which the set of bits to be retransmitted is adap-tively selected based on the estimated a posteriori(More)
To my parents and my sister ACKNOWLEDGMENTS First I would like to thank and express my sincere gratitude to my advisor, Dr. John M. Shea. This work would not have been possible without his expertise, hard work and patience. He guided me at each and every stage of my Ph.D. program and was always easily accessible. He read and revised all our conference(More)
A diesel engine is an internal combustion engine that uses the heat of compression to initiate ignition to bum the fuel, which is injected into the chamber. In this paper the various processes of the diesel engine processes are simulated by writing a C program for the mathematical model developed for the various processes. Then the program is run with the(More)
