Paralēlajā traucējumu dzēšana CDMA (steidzamu)

[ghoney_23]

Lūdzu, pārbaudiet kodu un dariet man zināmu, ja IAM doin jebkura kļūda.Arī man ir nepieciešams piemērot lēni un ātri rayleigh izbalēšanu šajā modelī.

RKD signāls ir R = SAB N

Got aizstāj ar smiley.

Man ir vajadzīga steidzama palīdzība saistībā ar fedings
paldies jau iepriekš
