Common CP-OFDM transceiver design for low-complexity frequency domain equalization
(IEEE-Institute of Electrical and Electronics Engineers Inc., 2022)Common cyclic prefix-orthogonal frequency-division multiplexing (CCP-OFDM) groups multiple OFDM symbols and uses one CP to protect them in slow time-variant channels. However, due to this particular design of CCP-OFDM ... -
A novel delay-doppler-based channel estimation method in doubly-dispersive ocdm systems
(2024)Orthogonal chirp division multiplexing (OCDM) has recently emerged as a new candidate for the 6G waveform. In high-mobility wireless channels, the inseparability of the data symbols in both time and frequency domains makes ... -
Sparsifying dictionary learning for beamspace channel representation and estimation in millimeter-wave massive MIMO
(Institute of Electrical and Electronics Engineers Inc., 2023)Millimeter-wave (mmWave) massive multiple-input-multiple-output (mMIMO) is reported as a key enabler in fifth-generation communication and beyond. It is customary to use a lens antenna array to transform a mmWave mMIMO ... -
Using OMP and SD algorithms together in mm-Wave mMIMO channel estimation
(Springer London Ltd, 2022)Lens antenna array is considered as an effective beam selection mechanism in millimeter wave massive multiple input multiple output systems. Efficient channel estimation (CE) algorithms are required to use the advantage ...
