Orthogonal frequency division multiplexing with subcarrier number modulation (OFDM-SNM) has been recently proposed to improve the spectral efficiency (SE) of traditional OFDM system. In this paper, we propose a joint-mapping OFDM-SNM (JM-OFDM-SNM) scheme transmit signal vector constant length information bits by jointly considering activation patterns and constellation symbols. A low-complexity...

Being able to accurately control the interaction of spin waves is a crucial challenge for magnonics in order offer an alternative wave-based computing scheme certain technological applications. Especially neural networks and neuromorphic computing, approaches can significant advantages over traditional CMOS-based binary schemes with regard performance power consumption. In this work, we demonst...
