Generalized and flexible modulation options
(Institution of Engineering and Technology, 2020)
Flexibility support is critical for fifth generation (5G) and beyond radio access technologies (RATs) to meet diverse applications, channel conditions, and user requirements. Besides the flexible waveform design discussed ...
Foreword
(Institution of Engineering and Technology, 2020)
The most critical difference of the fifth generation (5G) mobile communication technology compared to previous generations is its ability to support a wide variety of services. In other words, the 5G technology is all about ...
Extensionless adaptive transmitter and receiver windowing of beyond 5G frames
(IEEE - Institute of Electrical and Electronics Engineers, Inc, 2020)
Newer cellular communication generations are planned to allow asynchronous transmission of multiple numerologies (waveforms with different parameters) in adjacent bands, creating unavoidable adjacent channel interference. ...
Joint random subcarrier selection and channel-based artificial signal design aided PLS
(IEEE - Institute of Electrical and Electronics Engineers, Inc., 2020)
A novel method for providing physical layer security (PLS) depending on the randomness of wireless channel is proposed. Specifically, a channel-based joint random subcarrier selection and artificial signal design are ...
Inter-numerology interference management with adaptive guards: A cross-layer approach
(IEEE - Institute of Electrical and Electronics Engineers, Inc., 2020)
The next-generation communication technologies are evolving towards increased flexibility in various aspects. Although orthogonal frequency division multiplexing (OFDM) remains as the waveform of the upcoming fifth-generation ...
Non-redundant OFDM receiver windowing for 5G frames and beyond
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Contemporary receiver windowed-orthogonal frequency division multiplexing (RW-OFDM) algorithms have limited adjacent channel interference (ACI) rejection capability under high delay spread and small fast Fourier transformation ...
Dynamic sidelobe multiplexing in beamspace MIMO systems
(IEEE-Institute of Electrical and Electronics Engineers Inc, 2020)
Recent studies on multiplexing concept over beamspace multiple-input-multiple-output (MIMO) can reduce the need for using phase shifters while keeping the directivity performance at similar levels. Thus, beamspace MIMO ...
A spatially adaptive antenna array for mm-wave wireless channel control with microfluidics based reconfiguration
(IEEE-Institute of Electrical and Electronics Engineers Inc, 2020)
Spatially adaptive antenna array (SAA) is an electronically scanned antenna array with capability of changing its physical location. This new capability allows SAA to control the wireless channel environment to increase ...
OFDM with hybrid number and index modulation
(IEEE - Institute of Electrical and Electronics Engineers, Inc., 2020)
A novel transmission scheme is introduced for efficient data transmission by conveying additional information bits through jointly changing the index and number of active subcarriers within each orthogonal frequency division ...
User pairing and power allocation strategies for 3D VLC-NOMA systems
(Institute of Electrical and Electronics Engineers Inc., 2020)
In this letter, we propose two novel, yet efficient, user pairing schemes for non-orthogonal multiple access (NOMA) in 3D visible light communication (VLC). Our analysis is carried out assuming different heights for the ...
