Architectural Layers & Waveform Pipelines

Schicht 1: Sub-THz & RF-Phased-Array-Frontend (GaN/InP PA / True-Time-Delay (TTD) / 140 GHz D-Band Active Arrays): Ultra-wideband signal generation, beam squint mitigation, and simultaneous transmission of communication and radar probing waves.
Schicht 2: Dual-funktionale Wellenformen & Basisband-DSP (OTFS / Cyclic Prefix OFDM / Ambiguity Function Shaping / 2D-FFT): Orthogonal modulation in delay-Doppler domains, low peak-to-average power ratio coding, and deterministic clutter cancellation.
Schicht 3: Gemeinsame Signalverarbeitung & Punktwolken-Extraktion (Range-Doppler Matrix / MUSIC & ESPRIT DOA / CFAR Detection): High-resolution angle of arrival estimation, velocity extraction, ghost artifact elimination, and 4D spatial coordinate synthesis.
Schicht 4: Multistatisches Mesh & 6G Sensing-as-a-Service (3GPP Rel-19 SBA / Sensing Function (SF) / NEF APIs / RIS Control): Cooperative radar data fusion across distributed cells, intelligent surface reflection control, and exposure of real-time environmental digital twins.

Electromagnetic Coexistence & Precision Sensing in ISACLayer

Next-generation 6G communications merge high-throughput wireless data with ultra-accurate radar sensing into a single hardware and spectral envelope. ISACLayer establishes the mathematical formalisms, phased array transceiver designs, and signal processing pipelines required for zero-interference dual-functional operation.
