Assigment 1 (A and B)

# 1.	
(a)
Find locations where each of the following types of could be received. Also draw the paths !
a.	Direct LOS 
b.	Reflected path one bounce
c.	Reflected path two bounce
d.	Difracted path
e.	Transmission through wall or window

(b) From these 3 figures, explain the differences and how the different frequency affect the channel behavior!

This is the source coding

# 1.	Path gain for 2-ray model

In the 2 ray mood model, which is simple simulation. The dB decrease tends to be stable and there is no diffraction in the 2 GHz, 28 GHz, and 60 GHz bands. No noise there.

# 2. Path gain for 3 GPP Umi LOS 
![](https://i.imgur.com/BKIx5Ce.png)

In 3GPP UMi LOS or in practice, there is some noise for all three signals with the same signal graph. There is a lot of noise when the signal reaches rarely more than 40 meters. The signal still tends to be stable.

# 3. Path gain for 3 GPP Umi LOS Incl. Ground Reflection

In 3GPP UMi LOS with Ground Refrection, the three signal forms experience a decrease in dB to a distance of 30 meters, then an increase in dB to a distance of about 45 meters, then decrease again and so on.
