Mobile connectivity has become not only essential but a necessity for many network users. The number of mobile subscribers is growing rapidly and the demand for more bandwidth and higher data rates continues to increase (CISCO Global Cloud Index (GCI), 2018). To support this demand, 5G systems promise to deliver a major paradigm shift with respect to previous wireless communication systems using new technologies such as Massive MIMO (Andrews et al., 2014;Larsson et al., 2014). MIMO technology has been a breakthrough for wireless communication systems in terms of increased reliability and higher data throughput and it is imagined that more benefits could be harvested from scaled-up versions (Rusek et al., 2013).In Marzetta (2010), the author introduced the concept of Massive MIMO and demonstrated that an excessive number of radiating elements (M) at the transmitting side paired with a number of active users (K) permits the use of simple linear precoders and increases the overall spectrum efficiency. In Björnson et al. (2016), Lu et al. (2014), Ngo et al. (2013), Rusek et al. (2013, an overview of Massive MIMO technology is thoroughly presented alongside its main advantages and challenges. Massive MIMO systems can eliminate the effects of small-scale fading and uncorrelated noise thus reducing intercell interference. As a result, the corresponding channel is formed by a set of nearly perfect orthogonal subchannels (Narasimhan & Chockalingam, 2014). Even though MIMO systems are already operating worldwide, largescale MIMO has only been tested in labs (

“…Polarization diversity (PD) is regarded as a spatial efficient and effective alternative to SD in Non-Line-of-Sight (NLoS) environment because the signals transmitted through two orthogonal polarizations are independent [ 13 ]. F. Challita et al [ 14 ] have investigated the performance of PD for a massive MIMO system in industrial environment to address the problem of cross-polarization discrimination. F. Challita et al [ 15 ] have reported significant improvement in spectral efficiency in PD based massive MIMO system for Industry 4.0 applications.…”

With growing interest in Industry 4.0, machine-to-machine communication (M2M) will become the key enabler for low-power wide area networks (LPWANs) in connecting machines and sensor nodes distributed across a distance in the industrial environment. The choice of modulation and diversity techniques, and the selection of spectrum (licensed/unlicensed) will impact and influence the requirements of wireless M2M systems. Link reliability is one of the most important requirements for LPWAN deployment in industrial scenarios. Rotating Polarization Wave (RPW) system has been recently proposed as an LPWAN solution for reliable M2M communication in high clutter environment and it deploys BPSK modulation with polarization diversity (PD). This paper proposes a new multi-level Rotating Polarization Phase-Shift Keying (RP-MPSK) modulation to provide high data rate and energy efficiency. A novel quaternion model for RPW system (Q-RPW) is also proposed to reduce the complexity in modeling, simulation, and implementation. Results using Q-RPW model show that RP-MPSK modulation offers a high diversity gain over BPSK with second-order diversity. Bit error rate (BER) performance of RP-MPSK modulation compared against other LPWAN modulation like MPSK, FSK and QAM has shown high reliability and substantial improvement in SNR. To overcome the degradation in error performance caused by the proposed higher-order modulation, sampling rates are recommended based on BER performance. BER performance of RP-MPSK under multipath and interference conditions is also investigated.

“…This polarization is beneficial because multipath reflection results in the alteration of the polarization from horizontal/vertical to slant polarization, which consequently degrades the performance of the received signals due to mismatch polarization. An antenna with a ±45° slant polarization has many advantages because of its better gain diversity [1], higher channel capacity [2], [3], and lower bit error rate compared with horizontal/vertical polarization [4].…”
