Response between Pf (Probability of False alarm) and Pd (Probability of miss detect)
Response between energy detect and Probability of False alarm.
Use this as start point:
clear all; clc;
L=3;
sLen=10;
x=randn(sLen,1);
x=x/norm(x);
H=randn(L,sLen);
s=H*x;
thr=3;
nIter=10000;
pd=0; pa=0;
pd2=0; pa2=0;
for f=1:nIter;
y=s+randn(L,1);
if s'*y> thr
pd=pd+1;
end
end
for f=1:nIter;
y=randn(L,1);
if s'*y> thr
pa=pa+1;
end
end
plot(pa,pd,'*');
As i have referred the following reference IEEE paper
1. A Survey of Spectrum Sensing Algorithms for Cognitive Radio Applications
by Tevfik Y¨ucek and H¨useyin Arslan.
2, Building A Cognitive Radio Network Testbed by Zhe Chen, Nan Guo, and Robert C. Qiu
Use this as start point:
clear all; clc;
L=3;
sLen=10;
x=randn(sLen,1);
x=x/norm(x);
H=randn(L,sLen);
s=H*x;
thr=3;
nIter=10000;
pd=0; pa=0;
pd2=0; pa2=0;
for f=1:nIter;
y=s+randn(L,1);
if s'*y> thr
pd=pd+1;
end
end
for f=1:nIter;
y=randn(L,1);
if s'*y> thr
pa=pa+1;
end
end
plot(pa,pd,'*');
Sir can you suggest me a good paper in order to understand this matlab coding.
