Is BPSK better than QPSK in any way?

From Dr. Fuyun Ling: QPSK needs twice of SNR, but it can transmit twice of bits in the same unit time. Thus, they have the same Eb/No, so in this respect they are equivalent. In the spectrum ...

Is BPSK better than QPSK in any way?

From a hardware perspective, BPSK in general lends itself to less complex modulators, demodulators and carrier-phase-recovery circuits when compared to QPSK, due to the need for a quadrature not being ...
