Menghitung Kapasitas CDMA

Penjelasan :
Menentukan Kapasitas Maximal dan Nominal (M)
Processing gain (numeric) =  (Chip rate (Kcps)/Information rate (Kbps))
Processing gain (dB) = 10*LOG(Processing gain (numeric))
Eb/It (numeric) = 10^(Eb/It (dB)/10)
M maximum (omni) = (Processing gain (numeric)*Power control factor) / (Eb/It (numeric)*vf*(1+f))
M nominal / cell = (Processing gain (numeric)*Power control factor*Gain sektoral antena*Loading factor)/(Eb/It (numeric)*vf*(1+f))
M nominal / sector = (M nominal / cell)/3


Menentukan Eb/It
Processing gain (numeric) = Bandwidth (Hz)/Information rate (bps)
Processing gain (dB) =  10*LOG(Processing gain (numeric))
Pm (dBm) = 10*LOG (Pm (mW))
F (numeric) = 10^(F (dB))/10)
NoBw (mW) = F (numeric)*T (Kelvin)*Konstanta Bolzmann*Bandwidth (Hz)*1000
Sr (dBm) = 10*LOG(Pm (mW))+Lc (dB)+Gm (dB)+Gb (dB)+Lp (dB)+Mfade (dB)
Sr (mW) = 10^(Sr (dBm)/10)
Eb/It (numeric) = (Processing gain (numeric)*Sr (mW)) / (NoBw (mW) + (M -1)*vf*Sr (mW))
Eb/It (dB) = 10*LOG(Eb/It (numeric))
