This MATLAB simulation models 6G satellite networks with RIS-assisted links for joint communication and positioning. It incorporates MIMO-OFDM transmission, satellite-to-user channels, and 3D ...
Abstract: This paper presents a novel importance-aware quantization, subcarrier mapping, and power allocation (IA-QSMPA) framework for semantic communication in multiple-input multiple-output ...
Abstract: This paper presents a detailed simulation-based performance comparison of Orthogonal Frequency Division Multiplexing (OFDM) and filtered-OFDM (f-OFDM) systems in terms of Peak-to-Average ...
