Description: This paper examines the asymptotic (large sample) performance
of a family of non-data aided feedforward (NDA FF) nonlinear
least-squares (NLS) type carrier frequency estimators for burst-mode
phase shift keying (PSK) modulations transmitted through AWGN and
flat Ricean-fading channels. The asymptotic performance of these estimators
is established in closed-form expression and compared with the
modified Cram`er-Rao bound (MCRB). A best linear unbiased estimator
(BLUE), which exhibits the lowest asymptotic variance within the family
of NDA FF NLS-type estimators, is also proposed.

Description: III. USAGE
There is a sample script in the simscript directory. You will need
this and the file "rice_table.txt".
You should be able to run the sample script "ricean-sample.tcl". This
is just a slightly modified version of the example script
wireless-simple-mac.tcl which is in the NS distribution.
Parameters for the Ricean Fading: The fading model is used to
modulate the output of a large-scale fading model. In this case, it
uses TwoRayGround as the large-scale model.
For the Ricean Fading model:
MaxVelocity : This parameter determines the doppler spectrum.
The value of this parameter is the maximum speed of any objects in the
environment (could be nodes). It is NOT the speed of the
nodes themselves. This parameter should be specified before LoadRiceFile
