VALUE MOS NEMO OUTDOOR 5.2 vs NEMO HANDY 2.9

[px150]

Dear all fam

Help fellas i had trouble with MOS by NEMO , im using Nemo Outdoor ver 5.20 and Nemo Handy ver 2.9 ( N96 ) im curious bout MOS value..i already test with NO using teratec mediafire6 for mobile to mobile, that is true the NO shown the mos value bout 2.8 ( average ) and the parameter is stable..and the 2nd scenario im using NH ver 2.9 ( N96) for mobile to mobile...and same scenario script with NO and the result is, the mos value by NH very2 strange unstable ( sometimes didnt show the value ), and the value is more higher until 3.5 than NO.... how come i was read my tutorial the comparison NO (PESQ) and NH (PSM) less than 0.2 ?

please guys help me to solve this problem...

thanks

You can have one or two problems (depending on the version numers you're using)

1) You are using not an comformance (read correct filtered) sample

2) You're comparing different Pesq algo's to each other

sorry im not cleared

when i compared with nemo outdoor 5 ..it happened again but.the value between NO5 and NH2.9 not much as comparing NO4 and NH2.9, more decrease using NO5. im using the same scenario and lock the same band and channel but i still dont get it..why the nemo handy value more unstable ?

in your opininion sir DCA which the valid one for MOS measurement NO or NH ?

thanks

Use the ITU PESQ ref samples to get the answer straight.
Later versions of Nemo are using the P-S-Y-T-E-C-H-N-I-C-S dll and it causes trouble. Earlier versions using the O-P-T-I-C-O-M dll which is more stable. But it all depends on using the correct reference sample.

Can't tell if NO or NH is better, don't use NH myself

hi my i really need your help for MOS measurement i did with nemo outdoor5.3 and i have alot of test with sample reference in nemo 4s.wav the strange is that in all radio condition i cannot get mos more than 2 in average and the volume level for mobile at max but still the what could be reason
