Abstract
A method processes a concurrently triggered response signal at a number of transceivers configured to operate at a channel carrier frequency, where at least some of the transceivers have distinct transmit carrier frequencies offset from the channel carrier frequency. The method includes receiving, at a first receiver, a response signal in response to a trigger signal, the response signal including a combination of a number of transceiver response signals, each transceiver response signal of the number of transceiver response signals corresponding to a different transceiver of the number of transceivers and having a distinct transmit carrier frequency, wherein at least some of the transceiver response signals overlap in time, and determining characteristics of the number of transceivers based on the carrier frequencies of the transceiver response signals, including determining a number of transceivers in the number of transceivers.
