Teaching Styles



Slides plus black board

Slides can convey more information in an organized way

Blackboard is better for equations and prevents you from not coming.

A lesson from last semester: math
Course Website

Print handouts with 3 slides per page before you come

Homework assignment and solutions

Project descriptions and preliminary codes
Feedback

Too fast, too slow, small class advantages.

Reasons to be my students

Wireless Communication and Networking have great market

Usually highly paid and have potential to retire overnight

Highly interdisciplinary

Do not need to find research topics which are the most difficult
part.

Research Assistant, Stipend

Free trips to conferences in Alaska, Hawaii, Europe, Asia…

A kind of nice (at least looks like)

Work with hope and happiness

Graduate fast

Basic concepts

Simplex, half-duplex, and full duplex

Frequency division duplexing, FDD
– Most of system because of simplicity

Time division duplexing, TDD:
– indoor system only, because of delay

Different from FDMA and TDMA
