Abstract: Range ambiguity is a technical challenge for current spaceborne synthetic aperture radar (SAR) systems. To this end, a novel range-azimuth joint modulation transmission scheme is proposed, ...

OFDM_Modulation_Classification In this paper, we propose an automatic modulation classification (AMC) method for the OFDM systems with the presence of frequency-selective multipath fading, additive ...

Abstract: This paper presents a frequency-selective RF vector predistortion linearization system for RF multicarrier power amplifiers (PAs) affected by strong differential memory effects. Differential ...

AI-Assisted Adaptive Diffusion for Sustainable Channel Estimation (A-CDDCE). A PyTorch & MATLAB framework optimizing 2x2 MIMO-OFDM systems using a dynamic denoising controller, dual-axis attention, ...
