An Open‐Set Jamming Signal Recognition Method Based on Domain‐Specific Network
This study addresses the critical challenge of open‐set jamming signal recognition in complex environments by proposing a novel IQSpectro‐TransRes Joint Network with a specialised ArcCider Loss. The bi‐domain architecture and loss function collectively achieve a superior closed‐set accuracy of 98.22% while effectively identifying unknown interference ...

Adaptive Modulation Techniques for Duplex OFDM Transmission [PDF]
The design tradeoffs of turbo-coded burst-by-burst adaptive orthogonal frequency division multiplex (OFDM) wide-band transceivers are analyzed. We demonstrate that upon aiming for a higher throughput a higher proportion of low-quality OFDM subcarriers ...

Superposed IM-OFDM (S-IM-OFDM): An Enhanced OFDM for Integrated Sensing and Communications
Integrated sensing and communications (ISAC) is a critical enabler for emerging 6G applications, and at its core lies in the dual-functional waveform design. While orthogonal frequency division multiplexing (OFDM) has been a popular basic waveform, its primitive version falls short in sensing due to the inherent unregulated auto-correlation properties.

Generic Reduced-Complexity MMSE Channel Estimation for OFDM and MC-CDMA [PDF]
The performance of a decision-directed channel estimation scheme is analyzed in the context of both OFDM and MC-CDMA systems. A difficulty associated with the employment of the Least Squares (LS) approach to the problem of a posteriori channel estimation
