5.1. PHY Transmitter

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

Overview

The 802.11 transmitter core supports:

  • 802.11 a/g/n waveforms
    • NONHT OFDM (all rates)
    • HTMF 20MHz OFDM (MCS 0-7)
  • Sample-accurate per-Tx timestamps
  • Selection diversity per transmission
  • Radio agnostic interface
  • Simple digital baseband (IQ) and control interface
  • Flexible sampling rate support - up to 1/4 core clock frequency
