Which is more efficient BPSK or QPSK?
In comparison to OOK and BPSK, QPSK enables the data rate to be doubled while keeping the same bandwidth, meaning it's also possible to stay at the same data rate at half the bandwidth, with the same bit error ratio (BER). So QPSK is suitable for data rates of 100 Gbps as well.
Why is BPSK better than QPSK?
It provides low error probability. Bandwidth is twice efficient is compared to BPSK modulation. For the same BER, the bandwidth required by QPSK is reduced to half as compared to BPSK. It is more efficient utilization of the available bandwidth of the transmission channel.
What is advantage of QPSK over BPSK 1 point?
Advantages of QPSK:
It provides low error probability. Bandwidth is twice efficient is compared to BPSK modulation. For the same BER, the bandwidth required by QPSK is reduced to half as compared to BPSK. It is more efficient utilization of the available bandwidth of the transmission channel.
Why is BPSK and QPSK the same?
The probability of error is identical for BPSK and QPSK because the BER has been measured in terms of signal to noise ratio per bit.
