5.2. PHY Receiver

The PHY Receiver IP core implements a complete, real-time waveform-to-bytes pipeline in FPGA fabric. The core is implemented in Xilinx System Generator.

Overview

The current 802.11 receiver core supports:

  • 802.11a/b/g/n waveforms
  • DSSS (1-2 Mbps rates)
  • NONHT OFDM (all rates)
  • HTMF 20MHz OFDM (MCS 0-7)
  • Rx sensitivity better than spec
  • Detailed logging of every reception
    • Sample-accurate timestamp
    • Per-subcarrier channel estimates
    • CFO estimate
