Incorporation of Spatial Modulation in In VIVO Frequency Selective Nano Networks

Since Terahertz signals have proved their efficiency in ensuring safe human in-body based communications, future In-Vivo networks are envisioned to rely on them in order to ensure the forthcoming high-rate needs of the modern medicine. However, the propagation losses at these frequency bands are high. One viable solution for the quality of signal improvement is to enhance the spatial diversity through having recourse to multiple transmitting or/and receiving antenna elements. One undesirable, yet inherent, consequence of this is the generation of multi-channel interference (MCI). In this work, we propose to exploit the new spatial modulation technique with code division multiple access scheme to ensure a viable communication in In VIVO frequency selective Nano channels. The efficiency of the proposed scheme is highlighted through our simulation results.
