Radio over fiber communication system technology modulation techniques are presented in this study in order to enhance the performance behavior of optical fiber communication systems. The proposed modulation techniques used to meet this aim mainly consist from a mixture of traditional modulation technologies. The proposed modulation technologies include merging modulation techniques such as pulse...
Mobile robot navigation is a very important task in all robot applications from domestic service cleaning machine to highly sophisticated industrial robotic applications. In this paper, we investigated, and evaluated the well-known A* path planning algorithm. The standard A* algorithm is capable of finding out the most optimal path of the robot. A grid-based map obtained from the vision-based obstacle...
Vision-based robot navigation systems allow a robot to explore and to navigate in its environment in a way that facilitates path planning and goal-oriented tasks. The vision sensor is mainly used for obstacle detection and avoidance, object detection and tracking, and interaction with users. Usually these systems do not depend solely on vision sensors but use other sensors like sonar and laser range...
Navigation of autonomous mobile robots in unpredictable and dynamic environments is restricted by uncertainty, complexity, and unreliability issues of robots and their environments. In this context a navigation system for an autonomous mobile robot using intelligent fuzzy logic technique will be presented. Fuzzy logic control is able to emulate human experience about how best to control a system without...
Turbo codes are one of the best coding schemes for error correction because of their highest coding gain achievements. Number of iterations totally affects the turbo decoding process; it has an impact on the decoder performance, latency and power consumption. Dealing with battery-based devices requires paying attention to the battery life-time, consumed power, and hence the importance of a power efficient...
