Hi. Thank you for your reply.
With chanel Rayleigh fading and AWGN
%AWGN
n1 = 1/sqrt(2)*[randn(1,nr_data_bits) + j*randn(1,nr_data_bits)]*sigma;
%Rayleigh Channel
h1 = 1/sqrt(2)*[randn(1,nr_data_bits) + j*randn(1,nr_data_bits)];
y = h1*x + n1
How to include path loss based on distance (d)...
Dear
I am trying to simulate SISO communication with many relay serial.
y1 = h1.*x + n1; %Noise addition
r1=y1./h1; %Receiver
Please tell me how should I include path loss exponent in my simulation code? ( Path loss depend on dimension betwen Source and Relay)
Thank you...
About BER? I had BER for each branch ? How calculate BER at the destination, Graph BER vs overall SNR ?

Hi David, Please give me code
Thank David
I need simulate BER for collaborative dual-hop transmissions using maximal-ratio-combining (MRC) diversity in the destination.
The simulation result show that when have a Relay, BER will be better that direct communication. When increase number of relay, BER will decrease
as this...
Dear David
Thank you for your guide
I simulated BER for multihop without cooperative relay, but with cooperative relay for dual hop , I can't simulate it.
I need simulate BER for multihop with cooperative relay. With this case, when increase number of Relay (as photo), BER at destination will...

Re: Help me matlab code for performace of multihop with fixed relay
Thank you for your guide. It is very detail.
You made a code for dual hop with cooperative relay.
I need simulate Outage probability with increase number of hop in multihop sytem without cooperative relay as this paper...
Re: Help me matlab code for performace of multihop with fixed relay
Yes, I know
I can simulate BER for 1 hop, two hops, ...
But I don't know how to simulate Outage Probability for 1 hop , 2 hops .... Can you help me this problem
Can you talk with me via gmail chat : nguyenkimhieuha
Help me matlab code for performace of multihop with fixed relay
I'm working to evaluate performace of multihop with fixed relay.
Source --> Relay1 --> Relay2 --> Relay3 ...--> RelayN --> Dest
I need matlab code for simulate this problem ( evaluate BER, Pout)
Please see this paper ...
I'm working to evaluate performace of multihop with fixed relay.
Source --> Relay1 --> Relay2 --> Relay3 ...--> RelayN --> Dest
I have a question: I don't understand why BER will increase when number of hop increase. This problem will contrast with the advantages of multihop.
