**BER vs Eb/No plots for a coded system**hi,
hav anyone of you ever tried to make a BER vs Eb/No grpah for a conv
coded system?...in matlab or in simulink....what are the parameters
that u chose for the Conv encoder, AWGN channel block and for the
'viterbi decoder'?......and did the plot fit well with the
theoretical results?

**Ambiguity in Eb/N0 vs BER plot**I want to plot Eb/N0 vs BER bpsk demodulation in Matlab. I am using BPSK
modulated signal @ carrier frequencey 8KHz, data rate 1KHz. Sampling rate
is set
I have tried to use awgn function for adding noise. This signal accepts
Signal to noise ratio (SNR)in parameters. In order to convert into Eb/N0
for BPSK signal. I have used following relation
SNR = Eb/N0 + 10log(R/B) (This formula i have seen for Base Band
signal does it work for band pass as well)
R=data rate (1KHz in our case)
B= channel width (I have found in some literature that B=sampling
rate=96000Hz in our case)

**how to calculate noise vector from Eb/No to plot a EbNo/BER graph (noise generation)**Hi,
I'm doing a final project in OFDM simulation and I would like to plot
a EbNo/BER graph. For a range of a specified EbNo, I I have to
generate a noise added to the signal. I have no idea how I could
generate a noise vector from this Eb/No.
supose that my signal is x = randint(1,N)
some people generate noise vector by 1/sqrt*(randn(N)+jrandn(N))
do I have to multiply this with a constealltion number? or do I have
to multiply this with any OFDM process too???
Thank you very much for your reply. I'm a bit stressful right now
because I don't have a lot of time to finish it.

**BER plot**How can I do a BER plot for a simolation of OFDM PHY that I have the
..m files ?
Communications Toolbox - version 3, which is part of Release-14 (Matlab 7),
comes with a neat graphical user interface BERTool - it is designed to
provide exactly the same capability that you are looking for. Check out this

**Plot y1 versus x and y2 versus x on same graphic**Hi all
Suppose I wanted to (I don't actually; a colleague does) plot the
trend line for y1 vs X and the trend line for y2 vs X together on the
same axes.
How would I do so in SPSS? Is it possible just using the gui? (We
have a site licence for version 15.0.0.
Thanks.

**BER plotting in matlab**Hi,
I am trying to simulate a Reed-Solomon coding and decoding
simulation over AWGN.
My problem is that the line stop every time at SNR 7dB and
BER almost 5*10-5 but the target is to reach smaller than 10^-6.
I tried to run it for more time but the result is the same
if I run it 100 times and 1000 times.
Any suggestions?
Thanks.

**Generating BER plots**Hi,
I'm looking for a simple and painless method of generating BER plots
under Ptolemy II (SDF model). I experimented with the new
RunCompositeActor actor but I couldn't effectively record the last
reading of the "BER meter" at the end of the iterations. Maybe there is
a better way of doing this?

**LineSpec with plot(...) versus line(...)**Hi all,
Sorry if this is a dumb question, but is there a way to specify multiple properties (e.g. Color and LineStyle) for LINE the same way as is done for PLOT?
In other words, plot(x,y,'r--') works as expected, but line([x1 x2],[y1 y2],'r--') throws an error and must be expressed as line([x1 x2],[y1 y2],'color','r','linestyle','--').
Not a big deal, obviously, but it's a long-standing minor annoyance.
Thanks,

If you have the Communications Toolbox then there is a useful utility called bertool for doing this.

at the MATLAB command prompt to see if you have the tool.
If you do then read the doc for how to use it.

**plotting multiple solutions of ODE versus each other**I am using the ODE45 to solve for position of a satelite. I have x,y,and z equations. I plug in my equations adn get a t(time vector) and a position vector for each component. However, since they are different equations, the ode uses different step sizes to solve for each component. Thus, my t vector is different for all the components. HOw can I plot my x,y, and z vectors since they all use a different t? Any help would be greatly appreciated. I cant just plot them against each other b.c they are different sized vectors.

**Symbol rate versus BER question**
We have two digital modulations, both are the same, the only different is
the symbol rate.
Usually low symbol rate modulation have less BER than high symbol rate
modulation. But my question is if in the case of a bad carrier stability,
high symbol rate modulation could have less BER than low symbol rate
modulation. I think answer is YES, but i am not sure.

**plot of torque versus speed from simulink**Good day all.

I think that should depend on what kind of machine do you have, take
a DC motor for example, the speed is equal to J(moment of inertia)
multiple the derivative of the mechanical torque.
