well anni,

Ec/Io is the total Energy per chip divided by the total inference in the 1.25 Mhz spectrum(whole CDMA spectrum).It should be above a certain value so that the mobile can be distinguished by the BTS.

In CDMA Tech.

Forward Channels-

-Pilot Channel
-Paging Channel
-Sync Channel
-Traffic Channel

Reverse Channels-

-Access Channel
-Reverse Traffic Channel

Pilot Ch.- The pilot channel is used by the mobile unit to obtain initial system synchronization and to provide time, frequency, and phase tracking of signals from the cell site.

Moreover Pilot Channel uses Walsh Code 0(i.e. W0)

Paging Channel uses W1-W7
Sync Channel uses W32 &
Traffic Channel make use of W8-W31 & W33-W63.

But i can’t understand wats SOP??????
