## I need help for Matlab coding to calculate outage propability vs SNR in wireless sys

i have system and i want to write matlab code for this system to calculate outage probability vs SNR from relay to destination in defrent fading environment ( rayleigh one channel , nakagami onther channel ) can you please help me for that.

## amplification factor of Amplify and forward protocol

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

## Buffer aided Relay network

hi i want to simulate a buffer aided relay network with matlab. would any one help me , how can i simulate a (DF- thats my problem) relay network and how buffer work in this network and is there any specific code in matlab for it or what ?! thanks in advance

## Need Help Please! Simulate Quantize-and-Forward Multi-hop Relay (BER vs SNR)

Hi guys, i'm trying to simulate Multi-hop relay cooperative communication using Quantize-and-Forward to find BER vs SNR. The result isn't correct yet, and i'm really confused right now. I really need your help guys. Here's the matlab code i've made (just try to run it on your matlab): %BER vs SNR for Direct and QF multi-hop (...)

## single Relay simulation using QAM

Hi all I have code for single link (source- destination) using QAM simulation to produce BER curve. however I need to add relay node between source and destination and produce BER curve. can anyone help me with this please here is the code (matlab) M = 16; % Size of signal constellation k = log2(M); % Nu

## beamforming design for MIMO decode-and-forward relay channels

## relay placement or selection in networks matlab code

helo guys,, if any one having matlab code for relay placement in cellular networks .. plzz forward .. any related codes regarding relay placement or relay performance or simply relays also enough. plzz forwrd to me.. thnk you guys

## single relay, and Multi relay cooperative Communication matlab code ?

The concept of cellular radio is based on the cell, which was decided to be a hexagon(6 sided). This is an approximation to a circular cell. The intuitive cell shape would be a square, but this is extremely hard to do with aerials and would be expensive, if it is possible to do at all. A big transmitter can have a hexagon radiation patter. Many s

## Energy Efficiency of cooperative communication in Cellular Networks

## Decode and Forward in Matlab

Hi, can any one please help me to find the code of decode and forward strategy when using a relay station to transmit a signal from s1 to s2,in order to compare its SNR and BER to no-relay transmission ones please. Purpose is to show that transmission via relay is better than the direct transmission. PLease help..:(
