to my knowledge, ber performance of MMSE is not characteristized yet. In general, the average ber calculation involves intergration over snr, but snr for MMSE is not readily available.
I have been trying to find a mathematical equation that relates ber to snr for FSK. Could you also tell me how to relate Eb/N0 to snr and if i was to neglect the terms used (to relate them), what suitable values can i give them. Please do help.. I'm in a fix :(
i need matlab code for Spectral Efficiency and ber for awgn, rayleigh and rician channels(fading models). also if any material then please provide it.
Hi Who knows the relationship between snr and ber in a receiver? I think this relationship is depended on modulation type. Could anybody explain it? TX
hello people can anyone tell me how to plot snr vs ber for wireless communication channels using matlab code or simulink.. i ll be gratefull
what is the relation between snr and ber
hi all,, for non identical branch, there are snr for each branch so total snr is summation for all snr in each branch. what about ber, is it all summation for all ber in each branch, or it is the mean of all branch, or min. (...)
i have designed an ofdm system using qam modulation and plotted snr vs ber it comes around project is to use multiuser mimo and plot snr vs ber in matlab can u help me by attatching or sending coding to my mail id sowmia04@gmail.com. plz
I was trying to find a way to access the parallel port through matlab and I found this great library.I posted this after searching the boards for similar topics and didn't find this...I hope you find it useful.. IOlib - Hardware Input/Output Library for matlab and (...)
can you give me an installer of matlab? tnx ahead.
Hi, I have a question about OFDM : Does OFDM change the bandwidth , spectral efficiency and ber ? for Example : Does QPSK OFDM have same bandwidth , spectral efficiency and ber as QPSK or does it differ ? Thanks
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. (...)
Can ne one plz give me the matlab code for the simulation of 4QAM with snr vs ber graph? Waiting.... cheers
Dear all I need a matlab file (m file) simulates the snr versus the ber for the convolutional coder and Viterbi decoder with QPSK input if anybody can help please upload. Roshdy
hi guys !!1 i want to do ber vs snr plotting for 4QAM modulation ...but can you ls say what i really have to do in this case and can you pls provide me the code of matlab with some xplanation to this!!! i really badly need this ...have to do some homework! thanks in advance!!! pls xplain this..........

vl u pls mail me matlab code for snr Vs ber???
hi I have a question about MIMO simulation using matlab. suppose that we have a MIMO sysytem with N transmit antennas and M receiver antennas, and let H be the channek matrix. if we model H as a random matrix H:mxn and each elements belows i.i.d. complex gaussian(0,1), we will have: Y=Hx+N N:noise (...)
Hello! I need to simulate with matlab a QPSK modulation using Viterbi Coding. I need to obtain the theoricals graphs of the Eb/No and ber relationship for differents code rates (in fact, I need to obtain the graphs for Eb/No and ber relationship for a (...)
This can be the answer for your question. This is a matlab code. create a QAMSER.m file copy this into the file open and run it in matlab. You can change m (the modulation number), so you can calculate SER for any QAM channel with rayleigh fading. (by the way, it gives back the same (...)
Hi all, I hope you would be able to help me out. I have written a turbo code encoder and decoder in matlab with the specs below: Channel Additive White Gaussian Noise (AWGN) Modulation Binary Phase Shift Keying (BPSK) Component Encoders - Two identical recursive convolutional codes RSC Parameters n = 2, k = 1,K = 3 G0 = 7, G1 = 5 I
hai there, im verifiying my QPSK architecture and quit confuse on whether to choose snr or Eb/No in the AWGN block. is there any difference between snr and Eb/No to obtain ber? what is the difference if there are?
I am trying to calculate the ber of OFDM system, lets say using simplest BPSK modulation. I have experimental measurements of the channel impulse response, PDP with amplitudes and delay of the multipath components. I have formed OFDM symbols, modulated them and now it is time to pass them to channel. What is the most (...)
hello, I'm looking for the relationship between Eb/N0 and Es/N0 in the case of OFDM with QPSK. and also the relationship ber vs. snr / bit curve for QPSK OFDM over AWGN Channel THANK YOU VERY MUCH
Hi. There's a ".four" instruction in HSpice for calculating THD but it's not so accurate specially in SC circuits. So there's a very better solution. You can peak up your data from .lis file with printing desired information. then you should move this data to matlab? and do the FFT function there. after this moment you can (...)
Hi snr=10^(snr_final/10); ??? do you mean snr=10^(snr_db/10); Please attach your complite scripts. regards
in many calculations i have seen using variance of signals and noise for snr calculations. just wondering is variance representative of power or somewhat equivalent to it? please elaborate why variance is used instead of signal energy or power
Hi, i am trying to get plot between snr vs ber for Alamouti Scheme using 2 Transmitters and 1Receiver. But i am not getting proper output. i gone through through the procedure given in the IEEE paper "A Simple Transmit Diversity Technique for Wireless Communications". for the (...)

Hi all, I have just completed my previous task on simulating a fading process with a first order butterworth filter. What I did was to run the following space-state equation for 10,000 time points and taking FFT of it. x(k+1)=x(k)exp^(-wT) + w(k), where w(k) is noise Next, I am tasked to find the ber for a BPSK (...)

I try to implement the matlab code on ber for QPSK in OFDM over rayleigh channel (with n taps). However the result is a straight line. There must be something wrong in my code but I cannot figure it out what is wrong. Could you please help me to check it. I have to hand the work soon. Please please please help. Thank you (...)
In general if you have a total power P and N ransmit antennas, the power is divided uniformly, i.e.: each antenna transmits with P/N. for the normalization, it is usually done for simplicity of exposition without any loss of generality. If the power is not uniformly distributed, then you have P1, P2, ..., (...)
