Abstract
One embodiment of the present invention sets forth a technique for transmitting data in a listen before talk (LBT) wireless transmission regime. A digital radio receiver is configured to simultaneously receive and decode digital data transmissions from multiple radio channels. A digital radio transmitter is configured to listen to the multiple radio channels prior to transmitting digital data on a selected one of the multiple channels, based on locally determined channel occupancy. Optimal LBT efficiency is achieved within the set of multiple channels, thereby improving overall transmission efficiency between the transmitter and the receiver.
