“…In another work, a new two-dimensional geometric model is proposed in [6] for short range D2D channels. In [7], a MIMO channel model is proposed for THz frequency band to increase the communication distance by beamforming and increasing the communication capacity by spatial multiplexing, which have been shown to improve the Signal to Interference and Noise Ratio (SNIR) for THz communication systems. In [8], a distance-aware multicarrier modulation is presented to utilize the THz band distance dependency to improve the transmission distance.…”

The recent demand for connections to a huge number of users with very high data rates have motivated research communities to investigate communications into the higher frequency bands, such as millimeter waves and TeraHertz (THz) bands. Moreover, Subcarrier Index Modulation (SIM) has recently received a significant research efforts analyzing its different performance aspects. In this paper, we propose a SIM system operating over the THz band and analyze its performance considering mobile users and different resource allocation schemes. Specifically, Random WayPoint (RWP) mobility model is considered for users' mobility with different numbers of mobility dimensions, and three different spectrum resource allocation schemes, namely, fixed-order allocation, random allocation and distance-aware allocation are considered. Our analysis includes deriving mathematical expressions of both the average Bit Error Rate (BER) and the average Outage Probability (OP) for the three resource allocation schemes. Simulation results analyze different performance metrics like the BER and the OP and are shown to validate the accuracy of the derived expressions.

“…From the point of view of low-cost and low-complexity, the massive MIMO technology can maximize the communication quality of users with relatively less investment. Using the massive MIMO technology can reduce the interference between users and improve the system communication quality in the future THz application scenario [2].…”

As the preferred frequency band for future high frequency communication, the terahertz (THz) band has attracted wide attention. In this paper, an energy efficient resource optimization problem in THz band is studied. The massive Multiple-Input Multiple-Output (MIMO) technology and intelligent reflecting surface (IRS) are adopted to improve the capacity and energy efficiency (EE) of proposed network. An IRS assisted THz-MIMO downlink wireless network system is established. The original EE problem is decomposed into phase-shift matrix optimization and power allocation. On this basis, a distributed EE optimization algorithm is designed, which transforms the original nonlinear problem into a convex optimization problem. The simulation results reveal that the proposed distributed optimization method converges rapidly and abtains the maximum EE. This also proves that it is feasible and effective to apply both the IRS and the massive MIMO technology into THz communication network.
