【摘要或目錄】：
There are two parts in this lecture.
Part I, we will first introduce the mutipath propagation effects and Doppler frequency shift/spread effects.

After studying this note, students will be able to
1. Understand multipath channel effects in both time and frequency domains
2. Understand Doppler effects in both time and frequency domains
3. Understand multipath and Doppler effects in both time and frequency domains


Part II, we will briefly introduce multipath and Doppler channel models.

After studying this note, students will be able to
1. Understand multipath channel modeling in both time and frequency domains
2. Understand Time varying channel modeling in both time and frequency
domains
3. Understand key channel parameters:
delay spread & coherent bandwidth; Doppler spread & coherent time
4. Understand the definition of narrowband and broadband signals
5. Understand changing rate of channel characteristics
