Hi,
I have a strange problem. My simulatiuon plot is not lined with the x-axis. can anyone please help me for that.
I am attaching the script here and the plot.
Script:
close all;
clear;
clc;
% Defining variables
A = 10; % Total number of transmitters
p = 0.01;
Length_of_packet = 1000; % Maximum packet length in bits
Bitrate = 100; % bit rate for each transmitter in bits/sec
Trasmission_Time = Length_of_packet/Bitrate;
Total_Time = 1000; % Total time for simulation in seconds
Zero_slot_overlapping = 0;
One_slot_overlapping = 0;
Two_slot_overlapping = 0;
Three_slot_overlapping = 0;
Four_slot_overlapping = 0;
Five_slot_overlapping = 0;
Six_slot_overlapping = 0;
Seven_slot_overlapping = 0;
Eight_slot_overlapping = 0;
Nine_slot_overlapping = 0;
Ten_slot_overlapping = 0;
User = zeros(A,Total_Time);
for k = 1:A
%User(k,:) = zeros(1,Total_Time);
for i = 1:(Total_Time-4)
probability_of_transmission = rand(1);
if probability_of_transmission > p
User(k,i) = 0;
else
User(k,i) = 1;
end
end
end
for k = 1:A
X = sum(User(k,:));
end
for k=1:A
idx = find(User(k,:)==1);
[a,b] = size(idx);
for i = 1:b
for j = 1:Trasmission_Time
User(k, (idx(i)+j-1)) = 1;
end
end
end
Y = sum(User);
%Creating row pairs to compare
row_pairs = nchoosek(1:size(User,1),2);
%disp(row_pairs);
n_pairs = size(row_pairs,1);
n_overlaps = zeros(n_pairs,1);
%Finding overlapping and counting them
for ii = 1:n_pairs
n_overlaps(ii,1) = nnz(User(row_pairs(ii,1),:) & User(row_pairs(ii,2),:));

end

If you run this the plot is like this
