Feb 27, 2023 · Wireless Networks: Rake receivers are also used in wireless networks to improve the performance of the system, especially in environments where the signal is weak. Satellite Communications: In satellite communication systems, Rake receivers are used to detect and extract weak signals that have traveled long distances.
May 5, 2023 · In wireless communication, a rake receiver is used in CDMA systems and the radio signal when reflected from any type of obstacle will travel with a different type of amplitude, phase, and delay. The people behind the rake receiver are Price and Green.
The rake receiver consists of multiple correlators, in which the receive signal is multiplied by time-shifted versions of a locally generated code sequence. The intention is to separate signals such that each finger only sees signals coming in over a single (resolvable) path.
A rake receiver is a radio receiver designed to counter the effects of multipath fading. It does this by using several "sub-receivers" called fingers, that is, several correlators each assigned to a different multipath component.
The RAKE receiver receives the signals from multiple paths and combine them suitably with different appropriate delays. This way it recovers the transmitted signal. The complete principle of Rake receiver is explained in the figure. As shown first binary data is EX-ORed with the chip code.
Apr 1, 2012 · In wideband wireless communication systems the RAKE receiver is commonly used to collect the resolvable multipath energy and counter the effects of fading through diversity.
Rake reception is a diversity method that gained popularity mainly due to its use in second and third generation mobile systems. This paper reviews important and recent advances in rake diversity and its applications in wireless communications.
