                                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
