There are 64 forward (ie, downlink) physical channels in CDMA IS-95. They support 4 different kinds of logical channels (ie, 4 different kinds of information). What are the names of the 4, what...

The IS-95 forward connection channels and their characteristics are as follows
Pilot channel (PC): The pilot channel is transmitted by the base station for the purpose of timing
and sychronisation to the mobiles, and conveys no meaningful information. The "information"
conveyed by the channel is a persistent stream of zeros which is spread by Walsh code zero, which
itself a flood of zeros. This is additionally spread by a couple of quadrature PN groupings. This
implies the pilot channel is successfully the PN arrangement with its related counterbalance. An
estimation of the flag to-clamor proportion of the pilot channel likewise gives the portable a sign of
which is the most grounded serving segment.
Paging channels (PCH): This IS-95 channel is utilized to convey data to empower mobiles to be
paged. Information conveyed by this IS-95 channel incorporates framework parameters, voice pages,
SMS and other communicate messages. It possesses Walsh codes 1 - 7 subordinate upon the
framework necessities. The PCH conveys...
