Time-Asymmetric and Subcarrier-Specific Pulse Shaping in OFDM-Based Waveforms.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Vehicular Technology. Nov2015, Vol. 64 Issue 11, p5070-5082. 13p.

Abstract: In orthogonal frequency-division multiplexing (OFDM) systems, suppressing the out-of-band (OOB) emission with pulse shaping comes with a price. The expense emerges in designing the transition between consecutive symbols. The price can be either the red...

Artificial Noise Assisted Secure Transmission for Uplink of Massive MIMO Systems.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Vehicular Technology. Jul2021, Vol. 70 Issue 7, p6750-6762. 13p.

Abstract: Secure downlink transmission in massive multiple-input multiple-output (MIMO) systems has sparked great research enthusiasm. However, the secrecy of uplink transmission is equally important although relatively less attention has been dedicated to. In t...

Particle Filter Based Nonlinear Data Detection in Presence of CFO for Frequency Selective mmWave MIMO-OFDM Systems.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Vehicular Technology. Jun2021, Vol. 70 Issue 6, p5892-5907. 16p.

Abstract: The nonlinear distortions attributed by the radio frequency (RF) power amplifier (PA) and other RF circuits from the enormous bandwidth of millimeter wave (mmWave) and high frequency design limitations of the integrated circuits involved, degrade the p...

Design and Performance of a Novel Interference-Free GFDM Transceiver With Dual Filter.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Vehicular Technology. May2019, Vol. 68 Issue 5, p4695-4706. 12p.

Abstract: Generalized frequency division multiplexing (GFDM) as a sub-carrier filtered scheme can flexibly handle various different application scenarios of the fifth-generation system. However, due to the intrinsic self-interference resulting from the filter, t...
