    4242 * The channel estimation block computes a complex channel estimate (magnitude and phase) for each subcarrier per-packet. The equalizer applies the channel estimate per-subcarrier. The current Rx PHY uses the same channel estimates for the full packet. Extending this to a decision feedback scheme (where channel estimates are updated intra-packet) would be a straightforward extension.

    44 '''Multi-antenna support:''' The current PHY Tx/Rx pipelines are SISO, supporting only the modulation/coding rates specified in section 18 of the standard. We will add selecting diversity using the WARP v3 RF B interface soon. We're also considering implementing some of the MIMO modes from 802.11n. Let us know if these would be especially useful for your research.
