This paper aims at clarifying the role of the outer loop power control for CDMA satellite systems with on-board power constraints. If the inner loop of the power control is perfect, the channel turns into a AWGN channel and there is no need of the ou

A Bayesian decision rule for erasure insertion is derived, assuming frequency-hop multiple-access communications in Rician selective fading. The proposed method is based on a channel-identification approach together with decision feedback. Given the

Gallbladder cancer is a relatively uncommon malignancy. Its presentation is similar to that of gallstone disease and sometimes with non-specific symptoms. Laparoscopic cholecystectomy has become the method of choice for removing the gallbladder in mo

We propose a decision rule for symbol erasure insertion in a dispersive propagation environment based on Bayesian decision theory. The method is applied to frequency-hop communications with Reed-Solomon coding and error-and-erasures decoding. The pro

A compensation technique for nonlinearities is usually necessary in QAM digital satellite links. Analog waveform compensation has the advantage of reducing out-of-band spectral emissions with respect to end-to-end digital predistortion, in addition t
