The current MATLAB program of HHT includes the following modules:
1) eemd.m. The module that performs EMD/EEMD
2) ifndq.m. The module that calculates an instantaneous frequency for a given IMF and
3) extrema.m. A supporting module that is used by the previous two modules.
4) significance.m This is used to obtain the percenta line based on Wu and Huang
(2004).
5) dist_value.m This is a utility program being called by significance.m .

BCFO
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.
