Necessary Bandwidth

Bandwidth calculation method:

BW = R * (1/CR) * (1/Y)

where
BW = the necessary bandwidth, Hz
R = the baseband data rate, bits per second (bps)
= 150 kbps (kilo bits per second)
CR = the forward-error-correction (FEC) code rate
= 1/2
Y = the number of transmission bit per symbol
= 2 for QPSK

BW = 150k * (1/(1/2) ) * (1/2)
= 150k * (2) * (1/2)
= 150k Hz
