But I talk about the transmit power of node i to node j which is proportional to the distance of transmission. In the equation (1) of this paper https://people.rennes.inria.fr/Olivier.Sentieys/publications/2007/NBS07.pdf is the transmit power of the source to a destination D which distant d...
Hi all,
I want to know what is the formula of received signal by node j separed by distance d from a source i in wsn.
sometimes I find this formula: yij=hij * x+nij
in another yij=sqrt(p * gamma)* hij*x+nij ; where p is the source transmit power and gamma is the pathloss
another formula is...
Hi all,
I have a source and destination separed by a distance d=100m;
I suppose that the energy consumption of this communication is a linear function of distance E=k*d;
matlab code
d=0:100;
k=3;
E=k.*d;
plot(d,E);
now I want to insert a node N every 25m, so,
I get source and destination...
Hi all,
I have this equation of transmission energy between two nodes (SISO transmission).
Pout(d) = Eb*Rb × (4πd)^k/Gt*Gr*(λ^2)*Ml*Nf
where Eb is the mean required energy per bit for ensuring
a given error rate requirement
Rb is the bit rate
d is the transmission distance.
k power loss...
thanks for the response,
In fact I don't mean the difference in meaning ,I want the difference in use ,when we use one and when we use the other one?.In other way the equations of each one how I get the FER if I have the SER
thanks
Hi all,
in AF protocol the relay multiply the received signal from the source by an amplification factor
β=sqrt(P/(N0+P|hsr|²)
where P is the transmitted power,hsr is the channel 's vector between source and relay,
my question is about how to calculate |hsr|² if we have...
Hi,
please I want to know what is the difference between the Frame error rate(FER) and the symbole error rate(SER) ,if there is an exemple it is better.
then how we get the FER from the SER because I have a matlab code which calculate the SER and I don't know how can I calculate the FER from...
Hi all,
I have a matlab code that calculate the BER of BPSK modulation over a rayleigh channel I want to apply it to a sensor network ,how do I proceed.
matlab code:
% Script for computing the BER for BPSK modulation in a
% Rayleigh fading channel
clear
N = 10^6 % number of bits or symbols...
