Abstract
In a static channel, using a single-tap equalizer to eliminate inter-symbol-interference (ISI) and channel distortion makes multicarrier systems like Discrete Fourier Transform orthogonal frequency division multiplexing (DFT- OFDM) so attractive. Intercarrier interference (ICI) manifests as a result of OFDM transceivers' inability to diagonalize the channel matrix in doubly selective fading channels. The Discrete Fractional Cosine Transform (DFrCT-OCDM) has been proposed to act as the bases for Orthogonal chirp division multiplexing multicarrier (OCDM) system to perform better than conventional OFDM systems under doubly dispersive channel conditions. It is demonstrated that the DFrCT requires less intricate signal processing to implement than the traditional Fast Fourier Transform. Simulation findings show that the DFrCT offers better performance, spectrum efficiency, and energy concentration features than the conventional FFT technique. We propose an adaptive transmission in those channels utilizing dual-mode transmission of DFrCT-OCDM and DFT-OFDM. Its performances were analyzed using Monte Carlo computer simulations in time-variant and time-invariant channel scenarios.
