  Pulse Shaping  
 
The restriction for designing the pulse is that digital PAM chip sets are incapable of generating
pulses with a large time supportmore therefore in order to get cheap receivers/transmitters, the
time pulse is limited to 10Tb.
We use a Raised Cosine shape:
 
 


 
 


We use the following parameters for best fitting the frequency band [33.75GHz-34.25GHz]:

  • Maximum frequency = 50MHz
  • k = 0.1
  • Carrier frequency: f0 = 34GHz

The -3dB bandwidth of the passband signal is 96MHz.
