Hi,
In website"
"http://www.wirelesscommunication.nl/reference/chaptr05/cdma/rake.htm"
They said:
"The Number of Resolvable Paths
The order of diversity achieved by the rake receiver depends on the number
of resolvable paths L with
Tmax
L = round(------) + 1
Tchip
where Tmax is the maximum delay spread of the multipath channel."
and an Exercise
"Use the Nyquist Theorem for bandpass signals to explain that only delays
of integer multiples of the chip time are needed in a rake receiver."
But in other websites, they use half or quarter of one Tsymbol as
delay resolution for rake fingers.
I wonder know which one is right? and if the former, why use integer
multiples Tsymbols as delays in finger.

Thanks.
B.R.
