Dual band wireless transmission over 75-150GHz millimeter wave carriers using frequency-locked laser pairs
We generate and transmit 75-GHz-bandwidth OFDM signals over the air using three mutually frequency-locked lasers, achieving minimal frequency gap between the wireless W and D bands using optical-assisted approaches, resulting in 173. 5 Gb/s detected capacity.
Index Modulation Pattern Design for Non-Orthogonal Multicarrier Signal Waveforms
Spectral efficiency improvement is a key focus in most wireless communication systems and achieved by various means such as using large antenna arrays and/or advanced modulation schemes and signal formats.
An Experimental Proof of Concept for Integrated Sensing and Communications Waveform Design
This experimental work focuses on a dual-functional radar sensing and communication framework where a single radiation waveform, either omnidirectional or directional, can realize both radar sensing and communication functions.
Wavelet Classification for Over-the-Air Non-Orthogonal Waveforms
Composite statistical features are investigated and the wavelet enabled two-dimensional time-frequency feature grid is further simplified into a one-dimensional feature vector via proper statistical transform.
Deep Learning for Over-the-Air Non-Orthogonal Signal Classification
Experimental results indicate that transfer learning based CNN can efficiently distinguish different signal formats in both line-of-sight and non-line-of-sight scenarios with great accuracy improvement relative to the non-transfer-learning approaches.
