This video covers Pathloss Wireless Propagation Models • Free-Space Path Loss Model • Two-Ray Multipath Model • Path Loss Exponent Models • Single-Slope • Multi-Slope • To get the slides and additional resources. Please visit the course website or google • https://sites.google.com/view/muqaibe... • Here is the Matlab Code for the example: • % Dr. Muqaibel • clc • clear all • close all • d=[ 10 20 50 100 300]; • M=[-70 -75 -90 -110 -125]; • semilogx(d,M,'x') • xlabel ('distance, log scale'); • ylabel ('Power Ratio in dB') • axis([1 1000 -130 -50]) • d0=1; • f=9E8; • c=3E8; • lambda=c/f; • gamma=3.71; • K=20*log10(lambda/(4*pi*d0)); • d2=1:1000; • M2=K-10*gamma*log10(d2); • hold on • semilogx(d2,M2)
