IET Networks, EarlyView., 2023 We utilise a metaheuristic optimisation method, inspired by nature, called the Lévy‐flight firefly algorithm (LFA), to tackle the power regulation and user grouping in the NOMA systems. Abstract The non‐orthogonal multiple access strategies have shown promise to boost fifth generation and sixth generation wireless networks' spectral efficiency and ...

Adaptive equalization of multiple-input multiple-output (MIMO) channels [PDF]
2000 IEEE International Conference on Communications. ICC 2000. Global Convergence Through Communications. Conference Record, 2002 The paper proposes and investigates a new approach to adaptive spatio-temporal equalization for MIMO (multiple-input multiple-output) channels. A system with n transmit and m (m/spl ges/n) receiver antennas is assumed. A decision feedback equalizer is considered.
