“…Besides, F-GSM achieves a higher data rate than the conventional SM and the generalized-SM with a lower number of transmitting antennas. In [13], a technique called spatial permutation modulation (SPM) is proposed, which modulates the data bits into a permutation vector and activates the transmit antenna in successive time samples. SPM provides higher diversity gain and lowers BER compared to the conventional SM technique.…”

In this article, a high data rate and energy-efficient multiple-input multiple-output transmission scheme is considered by combining two popular and rational modulation techniques: spatial modulation (SM) and code index modulation-spread spectrum (CIM-SS). Since in the considered system, called generalized CIM-SM (GCIM-SM), incoming information bits determine modulated symbols, activated transmit antenna indices as well as their corresponding spreading code indices, data bits are conveyed not only by modulated symbols but also by the indices of the active antenna and spreading codes. Hence, a GCIM-SM scheme accommodates faster data rates while spending less transmission power and possessing better error performance compared to the conventional direct sequence spread spectrum (DS-SS), SM, quadrature SM (QSM), and CIM-SS systems. The mathematical expressions of the GCIM-SM system for bit error rate, throughput, energy efficiency, and the system complexity are derived to analyze the overall system performance. Besides, it has been shown via computer simulations that the GCIM-SM system has lower transmission energy, faster data transmission rate, and better error performance than DS-SS, SM, QSM, and CIM-SS systems. Performance analysis of the considered system was performed on Rayleigh block-fading channels for quadrature amplitude modulation technique.

“…Furthermore, compared to existing conventional MIMO in [16], number of possible conveyed bits of QSM is lower. Recently, a research on spatial permutation modulation (SPM) for MIMO systems has been published in [7]. The idea is to modulate information bits to a permutation vector and to activate the transmit antenna at consecutive time instants.…”

In this paper, we propose a novel index modulation mechanism called permutation channel modulation (PCM) by exploiting spatial resource of multiple input multiple output (MIMO). A set of permutation matrices is treated as indices to convey information bits by modulating a block of bits to a permutation matrix. Assuming that channel state information at transmitter (CSIT) is known, modulated permutation matrix is multiplied to the singular values of MIMO channel matrix obtained from decomposing the channel matrix using singular values decomposition (SVD). Besides to a permutation matrix, information bits are also modulated to constellation symbols. Therefore, the transmitted signals contain two sources of information: a permutation matrix and constellation symbols. At the receiver, transmitted symbols and a permutation matrix are detected using our proposed detection scheme. We derive the capacity expression and define the optimal capacity by finding the optimal power allocation at each transmission. As performance measure, capacity of PCM is compared with existing techniques. Using 4 × 4, we find that the capacity of PCM is doubled and remains superior with higher antenna settings. Our work creates a new paradigm of index modulation for multiple antenna transmissions by exploiting its spatial resource and significantly improves the capacity and outage probability performances.

In high-speed train (HST) communication, the application of 5G technology is of great importance. The massive multi-input multi-output (massive MIMO) technology in HST communication has advantages, but there are problems of inter-channel interference and multiple antennas synchronization. Spatial modulation has been widely used as a technology to solve this problem. In order to ensure the security of the HST wireless communication system, a hyperchaotic antenna-index spatial permutation modulation (HASPM) is proposed by combining chaos theory on the basis of spatial modulation technology. Aiming at the problem of reduced spectrum efficiency in traditional encryption algorithms due to pre-shared keys, channel information and noise interference, the proposed HASPM physical layer encryption scheme can improve above shortcomings on the basis of secure communication. The multipath fading effect is reduced, the bit error rate (BER) performance is greatly improved, and the system security and reliability are thus guaranteed. The evaluation results of calculation analysis and simulation on the scheme verified the feasibility and effectiveness of the proposed scheme.
