“…However, a significant amount of power is consumed for transmitting signal [1], especially when multiple transmit antenna elements work simultaneously due to the same number of transmit radio frequency (RF) chains. Driven by this, the spatial modulation (SM) technique has been proposed to reduce the cost of the multi-antenna systems [2]- [6].…”

Abstract-In this paper, the spatial modulation (SM) technique is employed at the source and relay nodes in a full-duplex twoway relay channel (FD-TWRC) to support spectral-efficient bidirectional communications while guaranteeing a low cost implementation. Maximum likelihood (ML) detectors are employed at each node that is subject to an intrinsic self-loop interference (SI). We first propose a tight upper bound on the average bit error probability (ABEP). Then based on the ABEP upper bound, an asymptotic ABEP expression is derived in the high SNR regime. Exploiting the asymptotic ABEP, an exact SNR threshold for the selection between FD-TWRC-SM and half-duplex (HD)-TWRC-SM is derived in a closed form, which sheds light on when it is beneficial to select the FD (or HD) mode. In addition, the power allocation (PA) among sources and relay is investigated, through which an optimal PA factor in terms of ABEP is obtained. All analytical results derived in this paper are verified by Monte Carlo simulations, from which some new insights are obtained on the performance of FD-TWRC-SM.

“…By contrast, the recent study in [28] has formulated an optimal mobile-traffic-aware BS deployment strategy to maximize the network's EE while meeting the users' outage probability requirements, for dense large-scale homogeneous cellular networks. Furthermore, the authors of [29] analyzed both the SE and EE of dense homogeneous cellular networks by considering the effects of the call arrival rate and by proposing a Markov-chain access model. A similar GaussMarkov mobile model was utilized for analyzing small cell backhaul networks in [30].…”

Abstract-In this paper, the energy-spectral efficiency (ESE) benefiting from the joint optimization of coordinated multipoint (CoMP) transmission and base station (BS) deployment are evaluated in the context of dense large-scale cellular network. We first derive a closed-form network ESE expression for a largescale CoMP-enhanced network, which allows us to quantify the influence of key network parameters on the achievable network ESE, including the BS density and the cooperation activation probability characterized by a CoMP activation factor as well as the users' behaviors, such as their geographical mobile-traffic intensity and average user rate. With the aid of this tractable ESE expression and for a given BS density, we next formulate a cellular-scenario-aware CoMP activation optimization problem whilst considering the users' outage probability as constraints to maximize the network's ESE. We then further jointly optimize the CoMP activation factor and the BS density to maximize the network ESE, again under the constraint of the users' outage probability. Our simulation results confirm the accuracy of our analysis and verify the impact of several key parameters on the network ESE. Finally, the ESE improvement of our proposed strategies is evaluated under diverse scenarios, which provides valuable insight into joint CoMP and BS deployment optimization in dense large-scale cellular networks.
