============ Summary of Hybrid MIMO ==========
MIMO is a key enabling technology in the currently emerging 5G systems and future 6G-plus paradigms, such as heterogeneous networks, millimeter-wave networks, vehicular sensor networks, among others. The highly desired properties of MIMO such as its ability to support high data rates, improve energy and spectral efficiency, as well as overcome the effects of shadowing and fading have made it increasingly attractive to the wireless communications industry. Nevertheless, a secure MIMO model with the required security levels to guarantee user information protection has still not been realized by the industry. In this work, we analyze the security technique used in developing a hybrid MIMO system with the ability to achieve both multiplexing and diversity gains. In the proposed technology special signal interference-canceling matrices are calculated using the channel’s variations and randomness between the user and receiver and are multiplied by user data at the physical layer level. Analysis indicates that the signal interference-canceling matrices provided absolute security (zero information leakage) against both internal and external eavesdroppers. Moreover, the new MIMO technique eliminates any processing at the receiver, where users directly receive their intended signals, consequently lowering complexity and power consumption at the receiver. These are highly desired properties for the internet of things (IoT) devices as well as 5G and beyond technologies.
