The packet error ratio (PER) is the number of incorrectly received data packets divided by the total number of received packets. A packet is declared incorrect if at least one bit is erroneous. The expectation value of the PER is denoted packet error probability pp, which for a data packet length of N bits can be … Visa mer In digital transmission, the number of bit errors is the number of received bits of a data stream over a communication channel that have been altered due to noise, interference, distortion or bit synchronization Visa mer As an example, assume this transmitted bit sequence: 1 1 0 0 0 1 0 1 1 and the following received bit sequence: 0 1 0 1 0 1 0 0 1, Visa mer The BER may be evaluated using stochastic (Monte Carlo) computer simulations.

The theoretical BER/OSNR curve of the single channel 110 GBaud PDM-QPSK is also plotted in Fig. 4(a) based on the additive white Gaussian noise (AWGN).
WebbBPSK and QPSK obtained similar result. Comparing their theoretical BER for AWGN equation, they are identical. Hence this result is correct. Even so, it can be observed that BPSK requires less signal power to obtain a 0 BER. GMSK BER performance is significantly higher than BPSK. This might be due to the Gaussian filtering. http://gdpspace.com/wp-content/uploads/Theoretical-BER-for-Common-Modulations.pdf
