BER vs Eb/No plots for a coded system
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
...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
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)
Fo...how to calculate noise vector from Eb/No to plot a EbNo/BER graph (noise generation)
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.
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

Can someone provide simple matlab script BER plots for different equalizers. It can just be analysed for BPSK modulation.
Transmit in AWGN channel creating 10000 bits' message to do random
and confirm BER and draw graph.
Length axis : BER
width axis: SNR
1 bit Energy of utility is Eb
AWGN mean 0, breakup No/2
Between SNR 1 ~ 6
1. When transmit BPSK
2. transmit BPSK after code using Hamming code in(7, 4)
3. transmit by QPSK
4. transmit QPSK after code using extended Hamming code in(8,4)
Point message creation and AWGN creation to observe turn program
about 4 case at the sun 1 times.
Is not doing at all as I am beginner helps please ask please.

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.

It is diffi...PLOTS versus POLYLINE
I have admittedly not tinkered around much yet with IDL's snazzy new graphi=
cs capabilities (map, text, polygon, etc), but was going to give it a try a=
nd convert a fairly simple program to the new format. In my example, a map=
is drawn, then various annotations are added, and lots of lines are added =
to the map (storm tracks). The tracks are in lat/lon coordinates of course=
, but must be treated carefully (I don't want to just throw the entire vect=
or of coordinates at it at once). Previously, I accomplished this with PLO=
TS (and /CONTINUE), and looped over the points...Generating BER plots
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?
