Lightning and other atmospheric noise interferes with Loran signal reception. This paper develops techniques to improve signal availability under these conditions.
Time Domain Method for Precise Estimation of Sinusoidal Model Parameters of Co-Channel Speech
Time Domain Method Sinusoidal Model Parameters Co-Channel Speech
2009/9/4
A time domain method to precisely estimate the sinusoidal model parameters of cochannel speech is presented. The method does not require the calculation of the Fourier transform nor the multiplication...

Adaptive Spatial Transform Domain FGS Coding
2010/12/17
In inter-picture coding, block-based frequency transform is usually carried out on the predicted errors for each interblock to remove the spatial correlation among them.
However, it can not always do...
