This paper proposes to exploit physical layer information towards improved rate selection in wireless networks. While existing schemes pick good transmission rates, this paper takes a step further towards computing the optimal bit rate. The main idea is to capture the channel behavior through symbol level dispersions, and "Replay" these dispersions on different rate encodings of the same packet. The "Replay" action can be emulated at the receiver without requiring the transmitter to send the packet at every other rate.
