EKF
非线性扩展卡尔曼滤波算法的matlab程序(Description:This is a tutorial on nonlinear extended Kalman filter (EKF).
It uses the standard EKF fomulation to achieve nonlinear state estimation.
Inside, it uses the complex step Jacobian to linearize the nonlinear dynamic system.
The linearized matrices are then used in the Kalman filter calculation.
The complex step differentiation seems improving the EKF performance particularly in accuracy
such that the optimization and NN training through the EKF are better than through the UKF )

papr_windowing
reduction to papr in ofdm with Peak Windowing:
The basic idea of peak windowing is to multiply the envelope of OFDM
signal with a weighting function . Therefore,
~xE (t)= xE (t) f (t)
where
XE(t) =[x(t)]
The weighting function given by:
f (t)= 1-Σ α .w(t- t )
t-t
w(t) : is the window function.
t : denotes the position of a local maximum of the envelop xE(t) .
α : attenuation constant .
When the amplitude of envelop amplitude of the OFDM signal exceeds a threshold, a window function is applied to the envelop of the OFDM signal to eliminate the peak amplitude. windowing results in a smooth signal.
Hanning window function will be used for w(t)
As a matter of fact , other windows such as cosine, hamming and Kaiser may be employed.
