1) Successive interference cancellation (SIC) is a PHY technique that allows receivers to decode packets that arrive simultaneously. While known in communications, emerging software radios make practical experimentation possible. 2) Contrary to initial expectations, SIC gains are not high when interfering bit signals are unknown beforehand. Advances in bitrate adaptation also squeeze the scope for SIC. 3) SIC benefits many-to-one transmissions like client uploads to an access point more than one-to-one transmissions. An SIC-aware scheduling algorithm employing client pairing and power reduction extracts more gains from SIC.
