The document presents simulation results for an LC-optimized PHY proposal for TGbb based on G.9991 PHY. It includes details on the simulation setup, frame detection results, header modulation, coding simulation results, payload modulation, and coding simulation results. The setup involved various repetitions and configurations for preamble, header, payload, and payload OFDM. The results highlight minimum SNR for detection rate, header parameters such as information bits, bandwidth, FFT size, cyclic prefix length, modulation, FEC code rate, and FEC block size.

  4. July 2019 doc.: IEEE 802.11-19/1054r2 Simulation setup See doc. 11-19/187r4: - Preamble: 100,000 repetitions, false alarm rate 0,1% - Header: 10,000 repetitions - Payload: 1,000 repetitions - OCR: 200 MHz Signal power is measured at red circle. The SNR is set by adjusting noise power in the following AWGN block accordingly. The impact of the Rx model on SNR is assumed to be neglibible, as the used bandpass cutoff frequencies exceed the signal bandwidth. Mate Hinrichs (Fraunhofer HHI) Submission Slide 4
