Signal Modulation Identification Based on Deep Learning in FBMC/OQAM Systems
Mobile Information Systems, Volume 2021, Issue 1, 2021., 2021 Signal modulation identification (SMI) has always been one of hot issues in filter‐bank multicarrier with offset quadrature amplitude modulation (FBMC/OQAM), which is usually implemented by the machine learning‐based feature extraction. However, it is difficult for conventional methods to extract the signal feature, resulting in a limited probability ...

Channel Estimation Approach with Low Pilot Overhead in FBMC/OQAM Systems
Wireless Communications and Mobile Computing, Volume 2021, Issue 1, 2021., 2021 In filter bank multicarrier with offset quadrature amplitude modulation (FBMC/OQAM) systems, a large pilot overhead is required due to the existence of the imaginary interference. In this paper, we present an approach to reduce the pilot overhead of channel estimation. A part of pilot overhead is used for transmitting data, and compensating symbols are
