Quantification and compensation of temporal decorrelation effects in polarimetric SAR interferometry

, 2012
Several studies showed that Pol-InSAR data especially at lower frequencies such as L- and P-band, are sensitive to the vertical distribution of scatterer along forest height.

Performance of Generalized Multicarrier DS-CDMA over Nakagami-$m$ Fading Channels

, 2002
A class of generalized multicarrier direct sequence code-division multiple-access (MC DS-CDMA) schemes is defined and its performance is considered over multipath Nakagamifading channels. The spacing between two adjacent subcarriers of the generalized MC
