The minimum bandwidth is thus 3Rb. Alternatively, you can choose two vastly different carrier frequencies and get two (spectrally non-overlapping) OOK signals occupying 2Rb Hz each for a total bandwidth of 4Rb Hz but with lots of unused frequency spectrum separating them.

What is the bandwidth required for coherent FSK?
The bandwidth of the periodic FSK signal is then 2f + 2B, with B the bandwidth of the baseband signal. The bit error probability can be shown to be pϵ = 1 2 e−E/2η , which under normal operating conditions corresponds to less than a 1dB penalty over coherent detection.
What is the minimum bandwidth required for PSK?
For PSK the baud rate is the same as the bandwidth, which means the baud rate is 5000. But in 8- PSK the bit rate is 3 times the baud rate, so the bit rate is 15,000 bps.
What is the relationship between the minimum bandwidth required for an FSK system and the bit rate?
The minimum bandwidth required for an FSK system is approximately twice of themaximum frequency deviation plus the bit rate.
What is minimum bandwidth required for BPSK?
Bandwidth of BPSK:
Thus the minimum bandwidth of BPSK signal is equal to twice the highest frequency contained in the baseband signal.
