Integrated sensing, communications, and computing (ISCC) has emerged as a key paradigm for next-generation wireless networks. To unlock high spectral efficiency and flexible on-demand coverage of ISCC, non-orthogonal multiple access (NOMA) and uncrewed aerial vehicles (UAVs) are considered promising enabling technologi...

To address the severe path loss, wideband beam squint effect, and near-field spherical wave propagation chal-lenges in Terahertz (THz) ultra-massive multiple-input multipleoutput (UM-MIMO) systems for 6G communications in this paper, we propose a true-time-delay (TTD)-assisted near-field wideband hybrid precoding schem...

The constructive interference (CI)-based block-level precoding (CI-BLP) approach reduces computational complexity compared to conventional CI-based symbol-level precoding (CI-SLP) and provides additional design flexibility due to its relaxed block-level design. However, using a constant precoding matrix within each blo...

Integrated sensing and communication (ISAC) greatly alleviates the problem of spectrum congestion by sharing the hardware platform and spectrum resources. However, due to the broadcast characteristics of the wireless channels, a potential eavesdropping target may detect the confidential information sent to the communic...

Symbol-level precoding (SLP) can achieve remarkable gains in multi-user multiple-input-single-output (MU-MISO) systems, while its extension to multi-user multiple-input-multiple-output (MU-MIMO) systems offers even greater potential by exploiting the spatial dimensions at both the transmitter and receiver. However, exi...

In this paper, we propose an fluid antenna (FA)-enhanced interference exploitation symbol-level precoding (SLP) for downlink multi-user multiple-input single-output (MU-MISO) systems, focusing on transmitter-side fluid antenna systems (Tx-FAS) that allow flexible spatial correlation effects while preserving user portab...
