Non-Coherent Code Acquisition in the Multiple Transmit/Multiple Receive Antenna Aided Single- and Multi-Carrier DS-CDMA Downlink
SeungHwan Won,Lajos Hanzo +1 more
TL;DR: It is shown that the employment of both multiple transmit antennas and multiple subcarriers is typically detrimental in terms of the achievable NC acquisition performance, while that obtained by exploiting multiple receive antennas is always beneficial, regardless whether single-path or multi-path scenarios are considered.
Journal ArticleDOI
Non-Orthogonal Multiple Access for Unmanned Aerial Vehicle Assisted Communication
TL;DR: Non-orthogonal multiple access (NOMA) is investigated for aerial base station (BS) and results are presented for various environment settings to conclude NOMA manifesting better performance in terms of sum-rate, coverage, and energy efficiency.
Journal ArticleDOI
Energy-Efficient Non-Orthogonal Multiple Access for UAV Communication System
TL;DR: The numerical analyses of the proposed scheme signify a substantial increase in the energy efficiency of the NOMA based UAV-BS in comparison to the baseline scheme of Orthogonal Multiple Access (OMA).
Journal ArticleDOI
Multi-Set Space-Time Shift Keying and Space- Frequency Space-Time Shift Keying for Millimeter-Wave Communications
TL;DR: This paper introduces a novel OFDM-aided multifunctional multiple-input multiple-output scheme based on multi-set space-time shift keying (MS-STSK), where the information transmitted over each subcarrier is divided into two parts: STSK codeword and the implicit antenna combination (AC) index.
Journal ArticleDOI
Layered Multi-Group Steered Space-Time Shift-Keying for Millimeter-Wave Communications
TL;DR: The LMG-SSTSK tackles the propagation challenges of the high-attenuation mmWave frequencies by sub-dividing the users into multiple groups and allows more users to be served simultaneously in the downlink over the same time- and frequency-resources than a system dispensing with the proposed grouping technique.
