In this paper, we investigate the secrecy sum rate optimization problem for a multiple-input single-output (MISO) nonorthogonal multiple access (NOMA) system with orthogonal space-time block codes (OSTBC). This system consists of a transmitter, two users, and a potential eavesdropper. The transmitter sends information by orthogonal space-time block codes. The transmitter's precoder and the power allocation scheme are designed to maximize achievable secrecy sum rate subject to the power constraint at the transmitter and the minimum transmission rate requirement of the weak user. We consider two cases of the eavesdropper's channel condition to obtain positive secrecy sum rate. The first case is the eavesdropper's equivalent channel is the weakest, and the other is the eavesdropper's equivalent channel between the strong user and weak user. For the former case, we employ the constrained concave convex procedure (CCCP)-based iterative algorithm with one-dimensional search. While for the latter, we adopt the method of alternating optimization (AO) between precoder and power allocation. We solve a semidefinite programming to optimize the precoder and drive a closed-form expression of power allocation. The simulation results obtained by our method demonstrate the superiority of our proposed scheme.KEYWORDS multiple-input single-output (MISO), nonorthogonal multiple access (NOMA), orthogonal space-time block codes (OSTBC), security, precoder, power allocation

“…Finally, similar to the GSM scheme's combination with STBC and V-BLAST [43], [52], the proposed LCIT-GSM can also be combined with the classic MIMO schemes for the sake of striking further trade-offs between throughput, complexity and diversity, which is left for future work.…”

Low-complexity improved-throughput generalised spatial modulation (LCIT-GSM) is proposed.More explicitly, in GSM, extra information bits are conveyed implicitly by activating a fixed number out of transmit antennas (TAs) at a time. As a result, GSM has the advantage of a reduced number of radio-frequency (RF) chains and reduced inter-antenna interference (IAI) at the cost of a lower throughput than its multiplexing-oriented full-RF based counterparts. Variable-GSM mitigates this throughput reduction by incorporating all possible TA activation patterns associated with a variable value ranging from 1 to during a single channel-use, which maximises the throughput of GSM but suffers a high complexity of the mapping book design and demodulation. In order to mitigate the complexity, first of all, we propose two efficient schemes for mapping the information bits to the TA activation patterns, which can be readily scaled to massive MIMO setups. Secondly, in the absence of IAI, we derive a pair of low-complexity near-optimal detectors, one of them has a reduced search scope, while the other benefits from a decoupled single-stream based signal detection algorithm. Finally, the performance of the proposed LCIT-GSM system is characterised by the error probability upper bound (UB). Our Monte Carlo based simulation results confirm the improved error performance of our proposed scheme, despite its reduced signal detection complexity.

“…Therefore, the same performance of OSSK can be achieved in a massive MIMO with mobile stations rather than fixed stations in a conventional OSSK. Recently, spatial-multiplexing aided spatial modulation [17], RF-aided spatial modulation [18] and quadrature spatial modulation [19] have been introduced in literature to exploit the diversity of space-time block coding (STBC). The schemes exploit the diversity advantage of space-time block coding employing high performance compressive sensing detectors with substantially reduced complexity.…”

We investigate space shift keying, which is a simple form of spatial modulation. The bit error rate performance of line-of-sight (LOS) multiple-input and multiple-output (MIMO) was obtained in the literature with orthogonal subchannels for indoor millimeter-wave (mmWave) communications. It is essential to impose a rigid restriction on the distance between the transmitter and the receiver and antenna spacing to maintain orthogonal subchannels. However, in wireless communications, it is not viable to meet the strict distance requirements since user equipment is portable. We propose asymptotic orthogonal space shift keying with mobile stations. The asymptotic orthogonal space shift keying approaches orthogonal subchannels for a large number of transmitter and receiver antennas in correlated subchannels. This result is valuable for future wireless MIMO communications in mmWave frequencies. The massive MIMO renders the subchannel correlation symmetrical so that they can cancel each other. The example correlation model is employed for a numerical illustration. The proposed performance analysis is based on a large number of miniaturized antennas available in mmWave frequencies.
