Abstract: Embodiments of the present disclosure relate to methods, devices, apparatuses and computer readable storage media for signal source identification and determination. According to embodiments of the present disclosure, in response to detecting a signal, a device identifies at least one unit sequence from the signal. A bandwidth of each unit sequence is a common divisor of overlapping system bandwidths among a plurality of devices. The at least one unit sequence uniquely identifies a further device transmitting the signal. The device determines, based on the at least one unit sequence, the further device from the plurality of devices. As such, a device suffering interference due to atmospheric ducting can find out an interference source and perform an action to avoid the interference.
