English term or phrase: PROCESSING GAIN
Radi se o ekstruderu; nabrajaju se poruke koje se pojavljuju na zaslonu, tako da nemam kontekst.

...Add anti slip
Add anti static
Add Masterbatch
Add PROCESSING GAIN

Na engleskom sam pronašla značenje, ali ne znam na hrvatskom pa vas molim za pomoć.
In a spread-spectrum system, the process gain (or "processing gain") is the ratio of the spread (or RF) bandwidth to the unspread (or baseband) bandwidth. It is usually expressed in decibels (dB).
Puno hvala svima

1 SPECIFIČNOSTI PRENOSA SIGNALA MOBILNIM RADIO KANALOM

MC-CDMA
U MC-CDMA predajniku kodiranje poruka različitih korisnika obavlja se korišćenjem spreding kodova u frekvencijskom domenu. Pri tome se višestruki pristup ostvaruje na taj način što svaki korisnik ima sopstveni kod. Zahtijeva se da ovi kodovi budu međusobno ortogonalni radi izbjegavanja interferencije izmedju različitih korisnika (Multi-User Interference - MUI). Za downlink komunikaciju najčešće se koriste Walsh-Hadamard kodovi. Kodirani signali korisnika modulišu set podnosilaca. Drugim riječima, isti originalni simbol se prenosi različitim podnosiocima. Pri tome je pretpostavljeno da je broj podnosilaca jednak kodnom dobitku (processing gain). U principu, postoje dva načina kombinovanja MC modulacije i spredovanja u frekvencijskom domenu. Na Slici 5-6 je prikazan MC-CDMA predajnik j-tog korisnika za slučaj kada je trajanje simbola u svakoj od paralelnih grana isto kao i trajanje originalnih simbola.
