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 4Tb.
We use a Raised Cosine shape:
|
|
| |
The following parameters were used for best fitting the frequency band [2.050GHz-2.150GHz]:
- Maximum frequency = 25MHz
- k = 0.93
- Carrier frequency: f0 = 2.06GHz

Baseband Signal
The time supported of the pulse is limited to 4Tb. |

The bandwidth of the baseband signal is 20MHz. |
