Practical GFDM-based Linear Receivers
Ahmad Nimr, Marwa Chafii, Gerhard Fettweis
The conventional receiver designs of generalized frequency division multiplexing (GFDM) consider a large scale multiple-input multiple-output (MIMO) system with a block circular ma…
Unified Low Complexity Radix-2 Architectures for Time and Frequency-domain GFDM Modem
Ahmad Nimr, Marwa Chafii, Gerhard Fettweis
Most of the conventional multicarrier waveforms explicitly or implicitly involve a generalized frequency division multiplexing (GFDM)-based modem as a core part of the baseband pro…
Extended GFDM Framework: OTFS and GFDM Comparison
Ahmad Nimr, Marwa Chafii, Maximilian Matthe +1
Orthogonal time frequency space modulation (OTFS) has been recently proposed to achieve time and frequency diversity, especially in linear time-variant (LTV) channels with large Do…
