Abstract:
1. A method for data communication comprising: receiving, at a receiver of a first device via a channel of a communication medium, multiple data transmissions; determining, based at least in part on noise variability in the multiple data transmissions, a data transmission from among the multiple data transmissions having a preferred physical data rate; determining, by the first device, a length of a guard interval for the channel for subsequent data transmissions from a transmitter of a second device to the receiver of the first device via the communication medium, based at least in part on a length of a guard interval of the data transmission having the preferred physical data rate; and determining, by the receiver of the first device, a noise variability of the data transmission having the preferred physical data rate; and determining to adjust the length of the guard interval to a first fraction of the guard interval, in response to the noise variability being above a first high noise variability threshold.
