Vortrag: Basics of Digital Wireless Communication

introduction to software radio principles


The aim of this talk is to give an understandable insight into wireless communication, using existing systems as examples on why there are different communication systems for different uses.

Although wireless communication systems, like Wifi, GSM, UMTS, Bluetooth or DECT, are always surrounding us, radio transmission is often seen as "Black Magic".

Digital wireless communication systems differ significantly from analog system designs, although actuall transmission is still analog. Digital modulations, coding, filtering etc. enable highly scalable and adaptive wireless systems, making it possible to design quad-band LTE/UMTS/CDMA/GSM radios on a single chip.

The talk briefly describes system concepts, modulation and coding basics, along with the challenges of mobile communication systems.

This will include the following topics:
System concepts
Digital Modulations
Shannon–Hartley theorem
Channel coding principles
Channel Access
High Frequency basics
Radio Propagation
