Path loss and the power received using Matlab program

Path  loss and the power received using Matlab program

Program:- 

close all;

clear;

Pt=input('transmistion power in watt');

Gt=input('gain of transmistting antenna');

Gr=input('gain of the receiving antenna');

ht=input('Hight of Transmitter');

hr=input('Hight of Receiver');

f=input('freq in MHz');

d=input('Distance in km');

pt=10*log10(Pt);

pr=pt+Gt+Gr+20*log10(ht)+(20*log10(hr)-40*log10(d))-120;

disp('Recived power is');

disp(pr);

for i=1:1:d

PL(i)=40*log10(i)+120-((Gt)+(Gr)+20*log10(ht)+20*log10(hr));

end

disp('path loss');

disp(PL(i));

plot(PL);

xlabel('distance');

ylabel('path loss');

Output:-

Hight of Transmitter40

Hight of Receiver5

freq in MHz325

Distance in km15

Recived power is

  -80.8482

path loss

  103.0231
