Speech Title: Multi-layer Quadrature Modulation and its Application in Complementary Coded CDMA

Abstract: In an OFDM system, cyclic prefix (CP) has to be added to avoid multipath-induced inter-symbol interference (ISI) with a sacrificed bandwidth efficiency. Peak-to-average ratio (PAPR) may impair its performance further if a large number of sub-carriers are used. On the other hand, traditional multi-carrier modulation suffers a prohibitive complexity, which can not be implemented with currently available chip technologies. This work proposes a different way to implement multi-carrier modulation, namely multi-layer quadrature (MLQ) modulation, which can generate an arbitrarily large number of carriers with only two oscillators. As an application example, we apply MLQ modulation to a complementary coded code division multiple access (MLQ-CC-CDMA) system, whose multi-carrier transmission is based on MLQ modulation to mitigate ISI and multi-user interference (MUI) with ideal auto- and cross-correlations of complementary codes. Compared to a frequency domain (FD) CC-CDMA system, MLQ-CC-CDMA has a lower RF complexity. Compared to OFDM direct sequence (DS) CDMA and single carrier frequency division multiple access (SC-FDMA) CDMA schemes, MLQ-CC-CDMA achieves a higher spectrum efficiency (SE) with Rake and MMSE detection due to its multipath and multi-carrier diversity gains.

Speech Title: RF Learning and Cognitive Learning Theory and Methods for Electromagnetic Space

Abstract: Spectrum resources are national strategic resources, and electromagnetic space is the sixth dimensional battle space. Using machine learning to realize electromagnetic spectrum space cognition and decision making is the key for efficient utilization of spectrum resources and electromagnetic victory. Although relevant research has been conducted in this field, existing machine learning methods are simply applied under ideal conditions such as static spectrum environment and large amount of spectrum data labels, and the intersection of wireless spectrum signal processing and machine learning has not been explored from wireless spectrum characteristics, which cannot be applied to the actual dynamic and complex electromagnetic spectrum space. Considering the inherent characteristics of the wireless spectrum, such as the highly dynamic and the emergent nature of the electromagnetic spectrum environment and tasks, the difficulty of utilizing and migrating knowledge in the spectrum domain, and the large amount of spectrum data but few labeled samples and unguaranteed quality, this report proposes a new paradigm of machine learning in the electromagnetic spectrum space: cognitive learning, through an in-depth study of the mechanisms of RF learning and brain cognition. Based on this, the exploitation of domain knowledge is further explored and the theory of cognitive escape reinforcement learning is proposed. Finally, the practical effects of applying cognitive learning and escape reinforcement learning to spectrum intelligent control, UAV visual navigation and target tracking in the lab will be reported.

Speech Title: Reconfigurable Holographic Surfaces: A New Paradigm to Holographic Communications for 6G

Abstract: The future sixth generation wireless communications look forward to constructing a ubiquitous intelligent information network with high data rates. To fulfill such challenging visions, the reconfigurable holographic surface (RHS) is developed as a promising solution due to its capability of accurate multi-beam steering with low power consumption and hardware cost. Unlike the conventional phase-controlled antennas, RHS can control the radiation amplitude of the reference wave propagating on the metasurface by leveraging the holographic technique. Such amplitude-controlled holographic beamforming triggers new challenges since a new beamforming scheme needs to be developed to handle the complex-domain optimization problem subject to the unconventional real-domain amplitude constraints. Both analytical and simulation results verify the significant data rate improvement of the proposed scheme.
