Text of the note
Show as plain text (Turkish; formulas and drawings are not included)
2) Band width Efficiency
3) Max channel capacity (Shannon)
5) Peak to Average Ratio
(tepe gücünün ortalama güce oranı)
6) Adjacent channel interference (ACI)
→ komşu kanalda girişimi
Adjacent channel Power Ratio (ACPR)
Ne kadar küçükse o kadar iyi
Theoretically to achive any BER required SNR = A
practically '' '' A + k → implementing margin
8) Error vector Magnitude (EVM)
9) Modulation Error Rate (MER)
