[Other resource] nda DL : 0: 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.

[Internet-Network] ADD-CODE-ns2_ricean_dist DL : 0: 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 -III. USAGE There is a sample script in the simscript directory.
