Abstract At the present, the U.S. Army requires its moving platforms to transmit the estimate of their own position at a fixed interval over the existing communication links, the Tactical Internet. This approach places great demand on the system bandwidth because the position information of every moving platform had to be transmitted even when its track variance is within the specified position error limit. If the position error is small, it is not necessary to transmit the position update for...

Abstract Character comparison is far from a new concept. For decades, computer science has worked on Optical Character Recognition and handwriting recognition techniques, which are used in a myriad of applications. Much progress has been made in this field, especially with the more contemporary advancements in artificial intelligence. In these cases, we are trying to compare given input to a known set of characters; that is, we want to map image representation of a character to a text it...

Abstract Real-time systems (RTS) scheduling is an important component in real-time systems education and research. Dozens of well-known scheduling algorithms are introduced in many textbooks. It is desireable that, given a set of real-time task specifications, a dedicated software tool carries out the schedulability analysis and schedule generation. This thesis presents the design and development of such a tool. The tool implements some most popular RTS scheduling algrorithms, such as the...

Abstract Bose-Chadhuri-Hocquenghem (BCH) codes belong to a powerful class of cyclic block codes that can be used to improve the performance of a communication link by detecting or correcting errors. BCH codes are considered to be the best of the binary block codes and are commonly used as a Forward Error Correction (FEC) technique in military and commercial communcation systems. Since the discovery of BCH codes, many mathematicians have developed decoding algorithms that can be implemented in...
