Abstract
Millimeterwave (mmWave) techniques will be a key enabler for wireless communications to achieve high data rates. Additionally, Filter Bank Multi-Carrier (FBMC) with good spectral properties has also been regarded as an important transmission technique for future wireless communications. In this letter, we design and analyze an FBMC-based mmWave Multiple-input Multiple-output (MIMO) system. Specifically, we first pre-code quadrature amplitude modulation symbols in time to ensure that the MIMO technique becomes simple in FBMC. Secondly, we determine the optimal subcarrier spacing by maximizing the signal-to-interference ratio. Finally, using a lens antenna array combined with a simple channel estimator, we transmit data to the receiver. Simulation results show that FBMC can effectively support multi-antenna and mmWave techniques, providing favorable efficiency and reliability. Furthermore, we also verify that Alamouti's space time block code can provide considerable diversity gain.
期刊介绍：
The IEEE Signal Processing Letters is a monthly, archival publication designed to provide rapid dissemination of original, cutting-edge ideas and timely, significant contributions in signal, image, speech, language and audio processing. Papers published in the Letters can be presented within one year of their appearance in signal processing conferences such as ICASSP, GlobalSIP and ICIP, and also in several workshop organized by the Signal Processing Society.
