“…The most widely studied IM technique is spatial modulation (SM). In spatial modulation (SM), each Tx and/or Rx antenna can be used as a point in the spatial constellation [17,18]. In this way, in SM, the complete array of Tx antennas is used to convey extra information in addition to transmission of the conventional quadrature amplitude modulation (QAM) symbol transmission.…”

Vehicle-to-vehicle (V2V) communication networks are based on vehicles that wirelessly exchange data, traffic congestion, and safety warnings between them. The design of new V2V systems requires increasingly energetically and spectrally efficient systems. Conventional multiple-input–multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) systems have been used successfully for the last decade. However, MIMO-OFDM systems need to be improved to face future communication networks in high-mobility environments. This article proposes an efficient index modulation (IM)-based MIMO-OFDM system for V2V channels. The proposed transmission system is evaluated in high Doppler-spread channels. The results demonstrate that the proposed scheme reduces the required computational complexity in data detection and exhibits gains of up to 3 dB in bit error rate (BER) performance when compared to the conventional MIMO-OFDM system under the same conditions and parameters, along with achieving superior spectral efficiency. The results show the viability of implementing the proposed system in practical applications for high-transmission-rate V2V channels.

“…In a conventional MIMO system, the spatial dimension is used for diversity and/or multiplexing purposes. Nevertheless, recent research has shown the advantages of using the spatial dimension to modulate the transmitted signal [3, 4]. In spatial modulation (SM), the array of transmitting (Tx) antennas is considered as a spatial constellation, where each Tx antenna represents a point in this constellation.…”

“…Multiple input-multiple output (MIMO) transmission technique has been recognised as a key technology for the implementation of future wireless communication systems [1]. Spatial modulation (SM) is a MIMO transmission technique where the array of transmit (Tx) antennas is considered as a spatial constellation, then, each Tx antenna represents a point in that constellation [2]. Ideally, from each Tx antenna to each receive (Rx) antenna exists a different channel that identifies this path.…”

This paper presents three multiuser multiple input-multiple output (MU-MIMO) downlink transmission strategies based on the extended quadrature spatial modulation (EQSM) system for mobile communication. The three MU-MIMO precoding strategies utilised are block diagonalisation (BD), dirty paper coding (DPC), and a combined BD-DPC strategy. We analyse and compare the performance of these three MU-MIMO-EQSM schemes with the conventional MU-MIMO spatial multiplexing (MU-MIMO-SMux) system in terms of bit error rate (BER) and detection complexity considering correlated and uncorrelated fading channels. Results show that the BD-MIMO-EQSM and DPC-MIMO-EQSM systems outperform by 2 − 3 dB in BER performance their conventional counterparts with the additional advantage of a detection complexity reduction of up to 62% for the analysed cases. For the uncorrelated fading channel, the BD technique has better BER performance for a spectral efficiency (SE) of 12 bits per channel use (bpcu), while the DPC technique has better BER performance for an SE of 8 bpcu. Considering the correlated channel, DPC suffers a deep BER degradation of up to 30 dB compared with BD. However, still in this scenario, both proposed MU-MIMO-EQSM systems outperform their conventional counterparts. In terms of detection complexity, DPC has a complexity reduction of 77% as compared with the BD technique. The BD-DPC-MIMO-EQSM hybrid system heritages the low detection complexity of DPC with the advantage of all users in the system having the same BER performance.
