Basic Mathematical and Physical Principles of Radio Communication Systems
Người thuyết trình : Robert SOBOTWireless transmission of information over vast distances is one of the finest examples of Clarke’s third law, which states that “any sufficiently advanced technology is indistinguishable from magic”. Even though a radio represents one of the most ingenious achievements of humankind and is now taken for granted; for the majority of the modern human population (including some of its highly educated members), this phenomenon still appears to be magical.
In this lecture, I present fundamental concepts in physics, mathematics, and engineering that are needed to help us understand and model wireless transmission of electromagnetic signals between a transmitter and the receiver. The theoretical principles are explained by using an example of a classical heterodyne radio receiver topology, which is applicable to both analog and software defined radio architectures.
