Chirp-based multicarrier modulation [PDF]
, 2012 In this paper we demonstrate that in doubly-dispersive environments, a multicarrier (MC) system based on a fractional Fourier transform (FrFT) can achieve a better concentration of power near the main diagonal of the equivalent channel matrix compared to

Software-Based Analysis of Multi User Orthogonal Frequency Division Multiplexing (OFDM)
Jurnal Jartel: Jurnal Jaringan Telekomunikasi, 2016 The application of OFDM technology is still not fully implemented in the Telecommunication Study Program at State Polytechnic of Malang. This is because the application of this technology is applied to hardware. However, this can be overcome by simulating the OFDM technology through software.
