BER vs Eb/No plots for a coded systemhi,
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 plotI 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 plotHow 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 Release14 (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

PlottingHi,
I am trying to plot a series of randomly generated line segments. However for some weird reason the following code is not plotting all of them. For example, if I were to set the num variable to 3, it only shows either 1 or 2 lines. If i set it to 6, it only displays 4 lines... I'm lost!! If you need more parts of my code please let me know. Thanks.
for i = 1:num
if (i == 1)
axis([0 film_length 0 film_length]);
hold all;
end
X{i} = originX(i,1):0.1:endX(i,1);
Y{i} = slope(i,1) * X{i} + intercept(i,1);
p = plot(X{i},Y{i});

Plot and PlotsHi everyone,
I am trying to produce a graphic showing continent outlines,
coastlines etc, with a graticule and the footprint of a satellite
image. I can do all this by using MAP_SET, and then I use PLOTS to
plot a vector of the image coordinates. Using MAP_SET however, I can
only specify a STEREOGRAPHIC projection, when I want a POLAR
STEREOGRAPHIC projection.
To get a POLAR STEREOGRAPHIC projection I need to use MAP_PROJ_INIT
and then PLOT to display the graticule. However when I do this I cant
seem to get PLOTS to display the image footprint. I have converted my
image footprint coordinates...
plot in plot?Hi, I've a problem with the plot respectively imagescfunction. I
want to diplay a sketch in the same figure displayed by imagesc.
The problem is that the sketch does not consist of full matrix, it
are just a lot of points that have to be plotted. The points are
simply represented by one x& yvalue pair. By now i can display it
only using a forfunction and plot point by point  what needs a lot
of time.
Another approach was to change the linestyle of the plot and use
markers, but if choose the marker '.' the sketch gets to large
points.
Is there a way that "plot" d...
Plot y1 versus x and y2 versus x on same graphicHi 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

BER plotting in matlabHi,
I am trying to simulate a ReedSolomon coding and decoding
simulation over AWGN.
My problem is that the line stop every time at SNR 7dB and
BER almost 5*105 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.

PLOTS versus POLYLINEI 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 plotsHi,
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?

Peter

How do you plot multiple plots in an array with no space between plots?I have some data that I'd like to plot in 12 small square plots, and then arrange those 12 plots into a 4x3 rectangular array. The thing I'd like to do that I don't know how to do is simplify the 4x3 rectangular array by squeezing the plots together, such that there is no space between the plots: the righthand border of a plot should be coincident with the lefthand border of the plot to its right, and its lower border should be coincident with the upper border of the plot right below it. Imagine 12 squares on a checkerboard; that's what I'm aiming for.
As far as I ca...
PLOTS and the new PLOTHi all,
Can anyone tell me how the new PLOT() handles scalars/1element arrays
for X and Y? Or do you still have to use PLOTS?
If you have a graphic created with PLOT(/buffer), will a subsequent
call to PLOTS go on the right plot? Or will it try to go in a window?
Thanks!

plotting implicit plot.hi mans..
i need to plot a circumference so i need to plot in implicit form..
such as x^2+y^25x2=0..
so how can i do??
i find also this topic
http://www.mathworks.com/matlabcentral/newsreader/view_thread/21684
but it doesn't help me much..
i also tryed this:
plot(plot::Implicit2d(x^2+y^21, x = 1..1, y = 1..1))
and matlab find an error..
>> plot(plot::Implicit2d(x^2+y^21, x = 1..1, y = 1..1))
??? plot(plot::Implicit2d(x^2+y^21, x = 1..1, y = 1..1))

XOM versus BP versus MSFT versus NOVLSome food for thought.
Regrettably, I did not get a chance to catch a certain
primetime infomercial (and such is not directly relevant
to COLA anyway), but I can go on a more general rant
regarding oil companies  and other, more COLArelevant
companies.
First, identification of the oil/gas companies appears to
be limited to about 3:
XOM  aka ExxonMobil.
BP  British Petroleum
CVX  Chevron Corporation
(this according to http://finance.yahoo.com/q/co?s=XOM )
Total net income for all three: about $89.1B, of
which XOM corrals $43.64B  almost half.
