Re: Plotting System average capacity v/s number of users, ma
Dear,
I am also stuck in the similar problem as yours and want to draw various graphs like
1. rate sum capacity vs number of users
2. outage probability vs number of user
3. outage probability vs snr
have you able to solve the...
monte carlo simulation matlab communication
Hi, I am also trying to do the similar simulation. Have you been able to do it. If yes can you help me here in understanding the problem and its MATLAB code.
@arif khan
i have pm you a message earlier also and i hope you can help me here as well.
I...
matlab mimo simulation
Hi,sir you are a person who frequently upload the various codes (MATLAB) for us junior students. So I thought I might request you for a personal favour. Sir, I am a student of UG at NUST and wanted some help for my project. Actually as part of my thesis project i am...
Hi,
I am doing a project on radio resource management for wireless netaorks. I am new to the subject and hence needs some basic material on the subject along with some MATLAB code explaining the subject.
Any one working on the subject or had access to some of the material and can send me the...
map turbo equalization
Hi,
Any one working on turbo equalization using MAP algorithm.
I have a question about calculating the gamma or the transition probability. Is it different from MAP decoder and if yes then whats the difference and if you have a matlab code portion for calculating the...
viterbi decoding qpsk
Hi, Thanks once again. Things are getting clear. One more quiery is can we use the complex value for calculating the Euclidean distance or do we require to convert our complex values back to +-1 before getting into Viterbi decoding.
Thanking in advance

viterbi decode soft
Thanks for the reply. But please bear with me and can you please help me a little bit more and explain in a little more detail how I have to implement QPSK.
In BPSK, we transmit + 1 ,whereas for QPSK we transmit + 1 + j ( four points ) How can you calculate the Euclidean...
qpsk viterbi
Hi, can some one explain to me how the viterbi decoding is done for a qpsk system. I have not found any material on the net which explains the algorthym in detail for qpsk. ( i have understood the viterbi algorthym for bpsk). I shall be greatful if some one can help me in any...
Hi,
Could someone please tell me how to implement a decoder for a
tail-biting convolutional code? I've been working on it all week and
can't figure it out
I'm using a 1/2 rate, constraint length 3 encoder
initialized with the first 3 bits of message. The bits of the message
are then fed through...
channel normalization
Hi,
I am simulating BPSK in fading channel. I am using three taps channel.i.e
h=(1/sqrt(2)).*abs((randn(1,3)+j*randn(1,3)))
My quiery is that i have studied that the channel has to be normalizied for all such simulation. What does this mean and how it is done?
Is the...
Hi,
I am new to MATLAB and was trying to simulate BPSK and QPSK in matlab.
I had a queiry regarding noise scaling .Why the noise is devided by sqrt(1/ebno) and sqrt(2) . Here is sample programme
ebno_index=1:7
ebno=10.^(ebno_index/10)
....
noise=sqrt(1/ebno)*randn(1,100) % for BPSK
...
eb/no and variance
Thanks a lot for the response.
If i correctly understood ur answer then thats mean if there is QAM16 and not QPSK then the noise has to divided by sqrt(8).
Another quiery is if we assume that our signal power is not 1 and is say 2 then will our noise become...
