May 16, 2015 · RAKE Receiver RAKE receiver, used specially in CDMA cellular systems,can combine multipath components, which are time-delayedversionsof the original signal transmission.Thiscombiningisdone inorderto improve the signal to noise ratio (SNR) at the receiver. RAKE receiver attempts to collect the timeshifted versions of the original signal ...
The RAKE receiver structure can be derived directly from the multipath channel model: ideally, one RAKE finger is allocated to each multipath, maximizing the amount of received signal energy. A prerequisite is, however, that the RAKE has corresponding knowledge about the current channel parameters such as number of paths, their location (in the delay domain) and current (complex-valued) attenuation.
Mar 22, 2021 · The rake receiver in Figure \(\PageIndex{3}\) has two fingers, but the practical limit on the number is based on the expected delay spread of the multipaths divided by the chip duration. Only delays that are an integer multiple of a chip duration are needed in a rake receiver [21, 22].
a Rake receiver tracking the strongest multipath components in wide-sense stationary uncorrelated scattering (WSSUS) Gaussian channels with frequency-selective fading. Analytical SEP expres-sions of the Rake receiver are derived in terms of the number of combined paths, the spreading BW, and the multipath spread of the channel.
A Rake Receiver is a radio receiver which is designed for the purpose to counter the effects of multipath fading. Due to reflections from multiple obstacles in the environment, the radio channel can consist of multiple copies of the transmitted signal having different amplitude, phases or delays.
