Secured Hybrid Precoder Design Based on Generalized Triangular Decomposition Method

The researchers and scientists suggest the use of millimeter-waves (mmWaves) for upcoming communication systems that can provide 200 times more bandwidth than the existing technology to meet all the challenging demands of modern mobile users. Since the demands of mobile users are exponentially increasing with the passage of time, exploiting the upper part of electromagnetic spectrum become vital to attain high data rate, broadband device connectivity, extreme capacity and nominal latency for upcoming communication systems. However, certain degradation problems are realized by the higher frequency bands. Thanks to the shorter wavelengths of mmWaves, which allow the employment of multiple-antenna technology to generate narrow and directed beam, and enhance the propagation gain. Still security is considered as one of the primary issues and has got lot of attention from the researchers in the recent times. In this study we aim to develop a hybrid precoder design that can ensure secure mmWave massive multiple-input multiple-output (MIMO) communications by exploiting generalized triangular decomposition (GTD) method in digital domain. Our simulation studies also confirms the effectiveness of GTD scheme.
