Iterative Frequency Domain Equalization for MIMO-GFDM Systems

IEEE Access, 2018
This paper proposes a new iterative frequency domain equalization (FDE) algorithm for multiple-input multiple-output (MIMO)-frequency division multiplexing (GFDM) systems. This new FDE scheme is capable of enhancing the system fidelity by considering the

Frequency Domain Analysis and Equalization for Molecular Communication [PDF]

IEEE Transactions on Signal Processing, 2021
Molecular Communication (MC) is a promising micro-scale technology that enables wireless connectivity in electromagnetically challenged conditions. The signal processing approaches in MC are different from conventional wireless communications as molecular signals suffer from severe inter-symbol interference (ISI) and signal-dependent counting noise due
