A Delay Phase Precoder Design For Terahertz Massive MIMO Beyond 5G Communication System

The future of wireless communication systems beyond 5G (B5G) is expected to leverage the terahertz (THz) band to achieve unprecedented data rates. Delay phase precoding in massive MIMO beyond 5G is like making sure each antenna talks at the right time and in the right way to improve communication. The proposed technique leverages the distinctive characteristics of the THz band, such as highly directional transmissions and sparse channel responses, to mitigate channel impairments and enhance signal quality. The design aims to exploit the spatial domain by incorporating delay and phase adjustments, ensuring efficient signal transmission and reception. By leveraging the unique properties of THz frequencies and massive MIMO configurations, the proposed precoder design enhances spectral efficiency and system reliability, thus facilitating the realization of high-data-rate communication systems beyond the capabilities of current 5G networks. This technique helps reduce interference and makes wireless signals stronger and more reliable, which is super important for faster and better connections in the next generation of wireless technology. The impact of hardware constraints, such as phase shifters and analog-to-digital converters (ADCs), on the practical implementation of the proposed precoding algorithm are explored. The proposed delay phase precoder is designed to selects the optimal delay and phase precoding Matrix at the transmitter end. Our simulation results also validates the improvement in performance in terms of spectral efficiency and energy efficiency.
