Intelligent Reflecting Surface Assisted Beam Index-Modulation for Millimeter Wave Communication

Millimeter wave communication is eminently suitable for high-rate wireless systems, which may be beneficially amalgamated with intelligent reflecting surfaces (IRS), while relying on beam-index modulation. Explicitly, we propose three different architectures based IRSs modulation in millimeter communication. Our schemes are capable of eliminating the detrimental line-of-sight blockage frequencies.The termed as single-symbol beam index modulation, multi-symbol and maximum-SNR The principle behind these to embed information both classic QAM/PSK symbols transmitter beam-pattern. proposed use a twin-IRS structure construct low-cost scheme. We conceive optimal maximum likelihood detector low-complexity compressed sensing schemes. Finally, designed evaluated through extensive simulations results compared our analytical bounds.
