A carrier frequency is selected to be used to communicate information to a transceiver in a communication system. Selecting includes, on each of one or more carrier frequencies, transmitting a probe message to the transceiver. A frequency offset between any two adjacent ones of the carrier frequencies is at least about 8 MHz. One or more response messages are received from the transceiver, wherein each of the one or more response messages is a response to a received one of the one or more probe messages. The one or more response messages are used to determine which of the one or more carrier frequencies will be used to communicate information to the transceiver. In some embodiments, each of the probe messages includes a training sequence, and information included in the one or more response messages enables selection of one of a number of possible modulation schemes to be used.
