We address the problem of blind carrier frequency-offset (CFO) estimation in quadrature amplitude modulation,
phase-shift keying, and pulse amplitude modulation
communications systems.We study the performance of a standard
CFO estimate, which consists of first raising the received signal to
the Mth power, where M is an integer depending on the type and
size of the symbol constellation, and then applying the nonlinear
least squares (NLLS) estimation approach. At low signal-to noise
ratio (SNR), the NLLS method fails to provide an accurate CFO
estimate because of the presence of outliers. In this letter, we derive
an approximate closed-form expression for the outlier probability.
This enables us to predict the mean-square error (MSE) on CFO
estimation for all SNR values. For a given SNR, the new results
also give insight into the minimum number of samples required in
the CFO estimation procedure, in order to ensure that the MSE
on estimation is not significantly affected by the outliers.

videofig
A figure ready to scroll through and play videos. You can also draw any custom graphics on it.
(VIDEOFIG(NUM_FRAMES, @REDRAW_FUNC) creates a figure with a horizontal scrollbar and shortcuts to scroll automatically. The scroll range is 1 to NUM_FRAMES. The function REDRAW_FUNC(F) is called to redraw at scroll position F (for example, REDRAW_FUNC can show the frame F of a video).
This can be used not only to play and analyze standard videos, but it also lets you place any custom Matlab plots and graphics on top.
Jiro posted a great example on the Pick of the Week blog, along with a nice GIF animation so you can see it in motion:

EXAMPLE 1
Place this in a file called "redraw.m":
function redraw(frame)
imshow([ AT3_1m4_ num2str(frame, 02.0f ) .tif ])
end
Then from a script or the command line, call:
videofig(10, @redraw)
redraw(1)
The images "AT3_1m4_01.tif" ... "AT3_1m4_10.tif" are part of the Image
