What is the difference between BPSK and QPSK in terms of band utilization and bit error rate?

4PSK is usually called quadrature phase shift keying (QPSK).

In order to improve the frequency band utilization, the most effective method is to let a symbol transmit multiple bits of information.

Therefore, the frequency band utilization rate QPSK is good.

The formula of error rate BPSK is (1/2)erfc(sqrt(r)), and the number of QPSK is r/2.
