2) In the received signals with maximum power are time shifted and added. The block diagram of this method look like a garden rake and is called RAKE receiver.
3) A signal …

Rake Receivers:

For the Principle of RAKE receiver Refer (Explain RAKE receiver in CDMA) asked in May2015.

i) When CDMA systems were designed for cellular systems, the inherent wide bandwidth signals with their orthogonal Walsh functions were a natural for implementing a Rake receiver. The Rake receiver reduces the effects …
