Hi all, in AF protocol the relay multiply the received signal from the source by an amplification factor β=sqrt(P/(N0+P|hsr|?) where P is the transmitted power,hsr is the channel 's vector between source and relay, my question is about how to calculate |hsr|? if we have hsr=randn(1,N)+j*randn(1,N) i other way hsrr is a N complex n
Hi, I am working about incremental relaying on cooperative communication system. System model: Source S, relay R, destination. I need the Matlab simulation code for "Throughput" in incremental relaying of amplify-and-forward cooperative protocol, over Rayleigh fading channels). If you have, please send me (...)
sir, I am working on a cooperative diversity topic using AF relay, at which the received signal from the source is amplified and forwarded by the relay to the destination. I need the code for it so please mail email id is
How to write matlab code for finding the "Outage probability of Cognitive amplify and forward relay".
Basically, if the underlying fading channels are Rayleigh, then SNR follows exponential distribution. That is y0, y1, and y2 are all exponentials, where y0, y1, and y2 are the instantaneous SNR of the direct path, the first hop of the relay path, and the second hop of the relay path, respectively. After generating them, calculate the equivalent SNR
i am doing project on " cooperative communication in cdma" i have done some work using 1 relay and equal gain using amplify and forward protocol i want to do the next step for different gain for each path using amplify and forward protocol??? code is attached with this please any body is having idea (...)
Hi, I have trouble in programming AF cooperative diversity technique. I have the following MATLAB code, but the result does not match the theoretical results. I assumed that the power at the source is equal to the power at the relay. clear all; clc N=10^6;%Number of bits b=rand(1,N)>0.5;%Generate 0s and 1s s=2.*b-1;%NRZ SNRdB=0:2:
Hi all! I am working on a code to compare the scenario of bidirectional relaying with 3 nodes (sender , receiver and relay) in which the sender and receiver want to exchange their information via relay. I am working on amplify and forward and decode and forward case but they are giving (...)
how do you calculate the diversity gain of amplify-and-forward relays and decode-and-forward relay?
Hello, I'm trying to perform a simulation for a cooperative network that uses amplify and forward protocol in MATLAB and I find it very hard to produce a MATLAB code. The network consists of a source, a relay and a destination. I'll try to produce graphs mainly for BER and outage probability, not excluding any other graphs. If someone (...)
Hello, I am working on a cooperative diversity topic using AF relay, at which the received signal from the source is amplified and forwarded by the relay to the destination. Now, if we suppose that the source S has a single antenna, and the relay has N_A receive antennas, and we assume that the channels between S
Can anyone plz tell me about the way to calculate the capacity of channel in general and Specifically the capacity of amplify and forward relay method. waititng.....
