Abstract

Embodiments of the present disclosure relate to a method, system, apparatus, receiver module, and computer program product which may provide a power-efficient reception. In an example embodiment, at least one spectrum available for a desired communication may be scanned, and available communication channels may be categorized based on at least one determined channel property. A communication channel may be selected from the available communication channels based on the result of the categorization, and complexity of a receiver processing may be set based on the at least one channel property of the selected communication channel. Complexity of the receiver processing may be reduced in light of the property of the selected channel, so that power consumption may be kept low.
