How to calculate bit error rate in QPSK?

Transmitting a symbol takes twice as long as a bit (Ts = 2·Tb) which means that the bandwidth efficiency of QPSK is twice that of BPSK. Bit error rate (BER) of a communication system is defined as the ratio of number of error bits and total number of bits transmitted during a specific period.

How is BER calculated for QPSK?

TL;DR The theoretical BER of an ideal QPSK system is Q(√2EbN0) where Eb is the energy per bit and N02 is the two-sided power spectral density of the additive white Gaussian noise channel.

How do you calculate bit error rate?

The bit error rate (BER), or perhaps more appropriately the bit error ratio, is the number of bits received in error divided by the total number of bits transferred. We can estimate the BER by calculating the probability that a bit will be incorrectly received due to noise.

What is the error probability of QPSK?

The bit error probability is determined when the signal interference and Gaussian noise are applied to the input of the QPSK receiver. The interference is approximated by a sum of sine waves with constant amplitudes and uniformly distributed phases.
