I am generated three Rayleigh channel gains including path loss assuming all fixed links
PL1=108; % Path loss for BS-RS
PL2=102;% Path loss for RS-MS
PL3=118;% Path loss for BS-MS
%% Channel gains
H_BS1_RS1=(1/sqrt(2)).*[randn(1,N)+j*randn(1,N)]...
Hello every one:
I am working on multi-cell cellular network; Using Matlab I am able to establish a network of two tier cells with 19 BS and each BS has three sectors. Each sector has one directional antenna.
Now my question is that, let my sector of interest is 1 of BS 1. now other 18 BS are...
Lagrange multiplier
Hi I want to solve some optimization problem:
Can any one guide me how Lagrange multiplier can be used in MATLAB environment:
especially when there are 4 to 5 variables are present.
any example is helpful.
Re: who can help me? how can I learn cooperative communicati
Hi
I am simulating Detect and Forward but not getting better BER than Direct link.
I am setting equal power at source and rely lets half at source and half at relay.
it it ok:
Re: MIMO-OFDM
Hi
I have done some work on MIMO-OFDM. I am attaching a file as well. Can any body tell me how can i used multiuser using TDD in this script.
Thanks
TWO Tap Rayleigh Channel
Hi
Please see this code , I am confused how i added the two version of signal received from two Taps with one sample delay.Initially I have done IFFT of the signal with Four subcarriers.Please guide me.
x=transdata1;
taps=2;
p1=1;
p2=0.8...
MMSE Equalization
Hi
I want some stuff on MMSE equlizer. I want to implement in MCCDMA simulation can any body tell about how can I implement this.
Thanks.
Equilization at receiver
hi i msimulate the channel in this way
x=transdata1;%( BPSK)
%----------------------Channel-------------------------------------------
taps=3;
p1=1;
p2=0;
p3=0;
gain1=sqrt(p1/2)*[randn(1,length(x)) + j*randn(1,length(x))];
gain2=sqrt(p2/2)*[randn(1,length(x)) +...
delay in signal
hi iwant to produce delay in signal as i have:
N=10^6; % Bits of data_user1
data_user1= rand(1,N)>0.5; % Generation of data user1
x=data_user1
fs=1
p1=1;
p2=0.2;
p3=05;
gain1=sqrt(p1/2)*[randn(1,length(x))+ j*randn(1,length(x))];
gain2=sqrt(p2/2)*[randn(1,length(x)) +...
multipath fading wikipedia
hi
why u take variance 0.01 and how we pass signal through this channel, is just multiplying it or something else.
Please give me some detail.
Thanks and take care

multipath fading matlab
Thanks for reply but i can understand. can u give me example. taps mean paths.
lets I want to creat 4 paths and there power as well.
taps=4
delays[0 10 20 30];
pdb=[1 0.1 0.2 0.5];
signal= rand(1,100);
now how i added fadding.
Thanks and take care.
