Abstract
Systems, methods, and computer-readable media for detecting signals are provided. A method comprises determining a time-frequency representation for a received signal and partitioning the time-frequency representation of the received signal into a plurality of time-frequency partitions. The method further comprises determining an energy (e.g., a spectral energy) for each of the plurality of time-frequency partitions and detecting one or more signals within the received signal based on the energy (e.g., the mean spectral energy distribution) of the time-frequency partitions. In some embodiments, multiple signals received simultaneously within an input signal may be detected in unknown noise conditions.
