Performance Evaluation and Analysis of Millimeter Wave Communication System

Millimeter wave (mmWave) communication leverages the large bandwidth potentially available at mmWave frequency band to provide high data rate, and is proved to be a promising technology for future wireless communication. Prior work mainly investigates the partial performance instead of the overall mmWave communication system design and performance evaluation. Different from the existing work, in this paper, we evaluate the link-level performance of mmWave wireless communication system operating on a 39.5-GHz frequency band. We first propose a new transmission scheme based on orthogonal frequency division multiplexing mechanism for mmWave communication by taking the characteristics of mmWave into account. We design a long-term evolution-like frame structure and optimize some key parameters for the mmWave communication system to support higher data rate. Second, according to the designed frame structure, we design a reference signal and a synchronization signal, and develop a synchronization algorithm. Finally, the downlink performance of system information, control information, and user data is evaluated. Numerical results show that the mmWave communication is a promising approach to realize the Gb/s transmission rate.
