Product Description
Wireless Communication is fundamentally the art of communicating information without wires. In principle, wireless communication encompasses any number of techniques including underwater acoustic communication, semaphores, smoke signals, radio communication, and satellite communication, among others.
Thus the spotlight of this solution will focus on digital wireless communication. Every major wireless system being developed and deployed is built around digital communication including cellular communication, wireless local area networking, personal area networking, and high-definition television. This class is unique because it approaches wireless communication from the perspective of digital signal processing (DSP). No background in digital communication is assumed, though it would be helpful.
Wireless Digital Communication System is an practical approach to wireless digital communication. This approach makes wireless more concrete, avoids simply drowning in mathematics and useful for graduate students as well. Students build a practical foundation for further study and good preparation for industry.
