Abstract: As research on affine frequency division multiplexing (AFDM) advances, its coexistence with legacy orthogonal frequency division multiplexing (OFDM) systems remains largely unexplored.
Abstract: In high-speed railway (HSR) OFDM systems, achieving better channel capacity requires appropriate power allocation based on accurate channel state information (CSI). While existing deep ...
