A system of functions (signals) on the finite line, called the oscillator system, is described and studied. Applications of this system for discrete radar and digital communication theory are explained.

Home and building security are major concern in our daily life digital smart door lock (DSDL) have become an essential part of these systems. In this paper, a secure DSDL which can grant access to home with fingerprint is designed implemented. An Arduino Nano microcontroller board, finger print sensor servo motor been utilized for lock/unlock based on print. The automatic authenticate validate ...

The Association of American Universities (AAU) and the Association of Research Libraries (ARL) are working together, through a Task Force on Scholarly Communication, and in consultation with the Association of American University Presses, to ensure a robust system of scholarly communication in the humanities and qualitative social sciences. The Task Force seeks to address the economic challenge...

We describe the design and CMOS implementation of a baseband spread-spectrum communication system using chaotic signals for spreading digital data. The communication system uses a new chaotic modulation scheme called M-DCSK (Modified Differential Chaos Shift Keying). The M-DCSK scheme and its characteristics are analyzed for single user and multi user applications. Results from a VLSI implement...

In this paper we investigate the communication of children playing with an interactive digital storytelling system. What users say during their interaction with a digital storytelling system can tell us much about how they relate to the characters and how engrossed they are in the storytelling activity. We propose a communication annotation scheme that combines ideas about framing from research...

This textbook presents the fundamental concepts underlying the design of modern digital communication systems, which include the wireline, wireless, and storage systems that pervade our everyday lives. Using a highly accessible, lecture style exposition, this rigorous textbook first establishes a firm grounding in classical concepts of modulation and demodulation, and then builds on these to in...
