NN-Defined Modulator: Reconfigurable and Portable Software Modulator on IoT Gateways
Talkat 21st USENIX Symposium on Networked Systems Design and Implementation (NSDI '24) · 2024-04-16..04-18·
summary
Neural-network models replace handcoded modulators so an IoT gateway compiles a modulator once and runs it across heterogeneous boards via ONNX, with a transposed-conv + FC template derived from signal-space analysis. Evaluation shows comparable BER to standards, up to 4.7× speedup on Nvidia Jetson Nano and 1.1× on Raspberry Pi, and real over‑the‑air demos that generate ZigBee and WiFi packets compliant with TI CC2650 and Intel AX201.
