A rake receiver is a telecommunications receiver designed to mitigate the effects of multipath dispersion in a mobile communications link. It achieves this with several slightly delayed sub-receivers to synchronize the individual components of the multipath path. Each component is decoded independently, but in a final stage of the receiver are added constructively in order to make the most of each path. Normally you will get an improvement of the signal-to-noise ratio (or bit-to-noise ratio) in a multipath environment, even surpassing a "clean" environment.

The receiver is named after the analogy with a rake (rake in English). This subsystem is common in a wide variety of devices that use CDMA or W-CDMA access to the medium, such as mobile phones or equipment. for Wireless LAN networks.
