Abstract
Methods and systems for detecting and combining audio transmissions containing data are provided. In one embodiment, a method is provided that includes receiving multiple audio signals from multiple receivers. An audio transmission may be detected in a first subset of the audio signals and the audio transmission may contain data. A second subset of the audio signals may be identified with the strongest magnitude of the audio transmission. Portions of the second subset of the audio signals may then be combined to generate a combined audio transmission signal and the combined audio transmission signal may be decoded for further processing.
