A radio receiver designed to counter the effects of multipath fading; commonly used in devices such as mobile phones. Uses several sub-receivers, each slightly delayed, to tune into the individual paths a radio wave follows (multipaths). Each component is later combined to effectively strengthen the signal.

A rake receiver is a radio receiver designed to counter the effects of multipath fading. It does this by using several "sub-receivers" each delayed slightly in order to tune in to the individual multipath components. Each component is decoded independently, but at a later stage combined in order to make the most use of the different transmission characteristics of each transmission path.
