“…The average SEP of the proposed scheme can be calculated by substituting the above MGF in the SEP expression for M -PSK signaling given in (5), where we obtain the following for binary signaling (w 1 = 0 and w 2 = π): P e = 1 π π/2 0 1 1 + N (4−π)Es 2 sin 2 ηN0 (20) By letting η = π/2 and considering the SNR range of interest N Es N0 10, P e becomes proportional to…”

In this paper, transmission through large intelligent surfaces (LIS) that intentionally modify the phases of incident waves to improve the signal quality at the receiver, is put forward as a promising candidate for future wireless communication systems and standards. For the considered LIS-assisted system, a general mathematical framework is presented for the calculation of symbol error probability (SEP) by deriving the distribution of the received signal-to-noise ratio (SNR). Next, the new concept of using the LIS itself as an access point (AP) is proposed. Extensive computer simulation results are provided to assess the potential of LIS-based transmission, in which the LIS acts either as an intelligent reflector or an AP with or without the knowledge of channel phases. Our findings reveal that LISbased communications can become a game-changing paradigm for future wireless systems.Index Terms-Beyond massive MIMO, error probability analysis, large intelligent surface (LIS), signal-to-noise ratio, smart reflect-array, software-defined surface.

“…In order to compensate high path loss and efficiently exploit the sparse nLoS links, analog beamforming networks, which enable all available beamforming gains, are employed at both transmit and receive sides. The indices of the resulting radiation beams, instead of the indices of the transmit antennas in the SM scheme, can, thus, be used to transmit extra information bits, which is the essence of the proposed BIM system;  The BIM architectures studied in this paper, are applicable to any device-to-device communication systems, whereas the SSM in [27] works only for a single user uplink. This indicates that the proposed BIM here is also applicable to vehicle-to-vehicle communications.…”

In this paper, we propose a new architecture and performance analysis for beam index modulation (BIM) wireless communication implemented with the aid of analog beamforming. The BIM concept is presented in order to extend and adapt the spatial modulation (SM) concept to sparse wireless communication channel environments. It is shown that when compared with the conventional beamforming and SM strategies, the BIM system can achieve higher spectrum efficiency in high signal to noise ratio (SNR) and non-line-of-sight (nLoS) sparse channel scenarios. Furthermore, different to the previous spatial scattering modulation (SSM) work the proposed BIM architectures have reduced hardware complexity, and, importantly, in some nLoS sparse channel conditions the BIM can also outperform the SSM. The above findings were further validated by some demonstrative experiments that were conducted at 10 GHz.

“…A maximum ratio combining (MRC)-based VSM transmission scheme was proposed and analog precoder design was investigated to enhance symbol error rate (SER) performance in [33]. [34] proposed a spatial scattering modulation (SSM) for uplink mmWave communications and studied its bit error rate (BER) performance. However, it should be noticed that all these works were done from the error performance perspective and with a single data stream.…”

Spatial multiplexing (SMX) multiple-input multiple-output (MIMO) over the best beamspace was considered as the best solution for millimeter wave (mmWave) communications regarding spectral efficiency (SE), referred as the best beamspace selection (BBS) solution. The equivalent MIMO water-filling (WF-MIMO) channel capacity was treated as an unsurpassed SE upper bound. Recently, researchers have proposed various schemes trying to approach the benchmark and the performance bound. But, are they the real limit of mmWave MIMO systems with reduced radio-frequency (RF) chains? In this paper, we challenge the benchmark and the corresponding bound by proposing a better transmission scheme that achieves higher SE, namely the Generalized Beamspace Modulation using Multiplexing (GBMM).Inspired by the concept of spatial modulation, besides the selected beamspace, the selection operation is used to carry information. We prove that GBMM is superior to BBS in terms of SE and can break through the well known "upper bound". That is, GBMM renews the upper bound of the SE. We investigate SE-oriented precoder activation probability optimization, fully-digital precoder design, optimal power allocation and hybrid precoder design for GBMM. A gradient ascent algorithm is developed to find the optimal solution, which is applicable in all signal-to-noise-ratio (SNR) regimes. The best solution is derived in the high SNR regime. Additionally, we investigate the hybrid receiver design and deduce the minimum number of receive RF chains configured to gain from GBMM in achievable SE. We propose a coding approach to realize the optimized precoder activation. An extension to mmWave broadband communications is also discussed. Comparisons with the benchmark (i.e., WF-MIMO channel capacity) are made under different system configurations to show the superiority of GBMM.
