“…Then, this technique was further developed for the single-RF-aided SSK scheme in [19]. More recently, in [20] the optimal number of bits to be mapped to the TAs and to the APM constellation was investigated under the constraint of a fixed total throughput by the same authors based on a novel tight upper SER bound. However, these LA techniques suffer from symbol-to-symbol transmit power variation, which may cause signal distortion because of the amplifier non-linearity.…”

In this study, the authors investigate the benefits of phase-rotation-assisted precoding (PRP) technique in spatial modulation (SM) systems, which are based on maximum free distance d min . First, a closed-form solution of the maximumd min PRP matrix is derived for the scenario of having two transmit antennas (N t = 2). Moreover, two numerical methods are proposed for dealing with the case of N t > 2. The complexity of the proposed algorithms is presented. The authors simulation results show that the proposed PRP algorithms provide beneficial bit error ratio performance improvements compared with both the conventional SM and with the existing adaptive SM.

“…The scarcity of the wireless spectrum is the main factor that hinders the vision for wireless access everywhere anytime, and perhaps the toughest challenge that wireless research has to undertake. Overcoming this challenge requires innovations in various areas including novel ways for spectrum sensing and reuse, mechanisms for using higher frequencies such as 60 GHz and the visible light, novel ideas for dealing with interference, multiple-input multiple-output (MIMO), and generally more efficient protocols and systems [1][2][3][4][5][6][7][8][9][10][11][12]. MIMO technology promises a linear gain in capacity with the number of antennas [13], but it is yet to be adopted on a scale commensurate with its true potential [14][15][16].…”

In this paper, a new multiple-input multiple-output transmission technique called quadrature spatial modulation (QSM) is proposed and analyzed in the presence of imperfect channel estimation at the receiver. In QSM, conventional spatial constellation diagram of spatial modulation (SM) system is expanded to include both in-phase and quadrature components. As such, significant enhancement in the overall spectral efficiency is achieved while retaining all inherent advantages of SM technique, such as inter-channel interference avoidance, single radio frequency chain transmitter and low receiver complexity. It is shown that significant performance enhancements can be achieved as compared with SM, Alamouti, and spatial multiplexing systems. Besides, the impact of Gaussian imperfect channel estimation on the performance of QSM system is studied. A closed-form expression for the pairwise error probability of generic QSM system is derived and used to calculate a tight upper bound of the average bit error probability over Rayleigh fading channels with perfect and imperfect channel knowledge. Also, simple asymptotic expression is derived and analyzed. Obtained Monte Carlo simulation results highlight the accuracy of the conducted analysis.

“…At the same time, only one antenna is active at any particular time instant, which simplifies the overall system complexity, allows the use of single radio frequency (RF) chain and relaxes inter‐antenna synchronisation requirements. Thereby, these techniques attracted significant research interests lately to improve the received signal quality and enhance the overall system performance .…”

In this paper, the performance analysis of spatial modulation and space shift keying multiple‐input multiple‐output techniques over generalised α − μ and κ − μ fading channels with imperfect channel state information at the receiver is presented. In particular, the pair‐wise error probability (PEP) of the systems under study is derived. The PEP expression jointly considers the envelope and the phase distributions of the fading channels. The obtained PEP is then used to derive an upper bound closed‐form expression for the average bit error rate. The influence of the fading parameters (i.e. α,κ and μ) and the channel estimation error on the system performance are analysed and discussed through representative numerical examples. The correctness of the conducted analysis is validated by means of Monte‐Carlo simulations. Copyright © 2015 John Wiley & Sons, Ltd.
