Low Complexity Energy Efficiency Analysis in Millimeter Wave Communication Systems

Abstract: Millimeter wave (mm-wave) communication is widely recognized as a promising technology to deliver over Gigabit high data rate for future wireless networks. However, mm-wave system performance may be degraded if the operation mechanism is not properly designed, because mm-wave systems suffer severe path loss and very short coherence time. In this talk, we first try to answer what the key trade-offs in mm-wave communications, how to generate and parameterize analog beam codebooks. Then, we propose a low complexity spectral and energy efficient mechanism and show how it can avoid high overhead and delay and enable a much longer quasi coherence time. A phase-controlled point-to-point mm-wave system example is studied to illustrate the proposed concepts and mechanism and provide a suggestion for system design.
