Planar Gaussian Splatting with Bilinear Spatial Transformer for Wireless Radiance Field Reconstruction

Collection of recent wireless-communications and signal-processing papers (arXiv 2604.*). Key contributions include: BiSplat-WRF — a planar Gaussian-splatting framework with a bilinear spatial transformer for physically-aware wireless radiance field reconstruction, improving spatial power spectrum (SPS) synthesis (higher SSIM vs NeRF/prior GS methods); blind OFDM-ISAC using fourth-order tensors and constellation asymmetry for joint sensing and blind coherent demodulation under heavy co-channel interference; multimodal M-ISAC scheduling and tracking via a Lyapunov-driven heterogeneous mixture‑‑
