Table 3 Complexity of transmit filter as a function of occupied bandwidth
Carrier spacing | Occupied bandwidth (MHz) | Number of active carriers | Guard bandwidth (MHz) | Requirement on Tx filter rejection to meet 55 dB rejection (dB) | Length of baseband Tx filter |
|---|---|---|---|---|---|
15 kHz | 7.8 | 520 | 0.1 | 35.4 | 230 |
| Â | 7.2 | 480 | 0.4 | 30.5 | 52 |
| Â | 6.0 | 400 | 1.0 | 25.4 | 18 |
| Â | 3.2 | 240 | 2.2 | 20.4 | 6 |
