Abstract A new demapper is presented for communication channels that can be modeled with data-dependent noise on the received symbols. This includes optical and satellite channels with various types of distortion. The demapper incorporates the covari

The nonlinear power amplifier and the analogue output channel filter with nonconstant group delay add nonlinear and linear distortions to the satellite transmitted signal, respectively. Recently, there has been growing interest in using Wiener predis

Detection of slow moving targets for a scanning radar in the maritime domain is typically performed using non-coherent detectors with both pulse-to-pulse and/or scan-to-scan integration. Other processing options include coherent processing for slowly

In this letter, an efficient predistortion scheme is proposed to compensate imperfections in a satellite channel due to the nonlinear power amplifier and the output channel filter. The predistorter is a Wiener system consisting of the linear and nonl

In this work, a hardware testbed is proposed to validate predistortion schemes designed to compensate for imperfections in a satellite channel. Such imperfection arise due to the nonlinear power amplifier and output channel filter and it is crucial t
