ypical Communication Classes old days(1980s): Teach analog and digital communications in separate classes Networking was sometimes taught as a graduate class, but most people did not see much use to it Today: Most communication classes focus mainly on digital Some classes may teach some analog for"historical"reasons Networking classes are offered at both undergraduate and graduate levels MIT: one graduate level digital communication class and one graduate level networking class( 6.450, 16.3716. 263) This class will introduce concepts of communications and networking at the undergraduate level First attempt at combining concepts from both Importance of not thinking of the two systems as separate systems
Typical Communication Classes • Old days (1980s): Teach analog and digital communications in separate classes – Networking was sometimes taught as a graduate class, but most people did not see much use to it! • Today: Most communication classes focus mainly on digital – Some classes may teach some analog for “historical” reasons – Networking classes are offered at both undergraduate and graduate levels • MIT: one graduate level digital communication class and one graduate level networking class (6.450, 16.37/6.263) • This class will introduce concepts of communications and networking at the undergraduate level – First attempt at combining concepts from both Importance of not thinking of the two systems as separate systems Eytan Modiano Slide 4
Why communications in AA? AA Information Initiative Communications Software and computers Autonomous systems Computers are a vital part of an Aerospace system Control of system, Human interface Involves computers, software, communications, etc E.g, complex communication networks within spacecraft or aircraft Space communications is a booming industry Satellite TV, Internet Access Information technology is a critical engineering discipline These skills are as fundamental today as the knowledge of basic math or physics
Why communications in AA? • AA Information Initiative – Communications – Software and computers – Autonomous systems • Computers are a vital part of an Aerospace system – Control of system, Human interface – Involves computers, software, communications, etc. – E.g., complex communication networks within spacecraft or aircraft • Space communications is a booming industry – Satellite TV, Internet Access • Information technology is a critical engineering discipline – These skills are as fundamental today as the knowledge of basic math or physics Eytan Modiano Slide 5
