Hello
What is right definitons of CDMA2000 1X Drive Test parameters? >
This parameters is from Dingli Pilot Navigator software...
-1st Ec/Io
-2nd Ec/Io
-3rd Ec/Io
-4th Ec/Io
-1st Ec
-2nd Ec
-3rd Ec
-4th Ec
-Max Ec/Io PN
-Total Ec/Io
-Max Ec/Io
-Reference Ec/Io
-Max Ec PN
-Total Ec
-Max Ec
-Reference Ec
-Handoff State
What is right definitons of CDMA2000 EVDO Drive Test parameters? >
-1st C/I
-2nd C/I
-3rd C/I
-4th C/I
-1st SINR
-2nd SINR
-3rd SINR
-4th SINR
-Total C/I
-Total SINR
Thanks

-1st Ec/Io 1st Best Ec/Io of the PNs
-2nd Ec/Io 2nd Best Ec/Io of the PNs
-3rd Ec/Io 3rd Best Ec/Io of the PNs
-4th Ec/Io 4th Best Ec/Io of the PNs
actually the searcher finger in the rake receiver always search for the pilot strength of all the PNs in a defined way. The softwares reports the Ec/Io of all the PNs.
-1st Ec
-2nd Ec
-3rd Ec
-4th Ec
Just as RSCP in WCDMA. Ec is the measured energy of the PN
-Max Ec/Io PN
-Total Ec/Io
-Max Ec/Io
-Reference Ec/Io
Total Ec/Io is the combined Ec/Io of all the locked fingures at the rake receiver (Active), Max Ec/Io is the maximum Ec/Io of all the fingures in active set. Reference cell is the one which is primary cell (call origination or handed over to) The refernce Ec/Io may not be the best at a particular instant.
-Max Ec PN
-Total Ec
-Max Ec
-Reference Ec
-Handoff State
Simultaneous connectivity to two or more legs.

Same Definitions as for Ec/Io except a difference that in CDMA the Ec is a subset of interference and Ec/Io is always less than 0 and calculated before de-spreading whereas In SINR or C to I is just like C/I in GSM, are greater than 1 and calculated after de-spreading.
SINR and C/I are closely related with a small difference that C/I is carrier to interference ratio and SINR is Carrier to interference and noise ratio.
Thanks
