All BER curves follow the theoretical BER curve with small deviations. -Therefore, the BER does not depend on the number of bits transmitted. + The minimum SNR for which BPSK has 1 bit error depends on the total transmitted bits, so that for a larger number of transmitted bits, the SNR must be higher for the signal to be correctly reconstructed. -For example. when transmitting 100 bits, it is enough for the SNR to exceed 4 dB so that there is no transmission error, while for the transmission of 100,000 bits, the SNR must exceed 8 dB. +For example: when transmitting 5 kb, it is enough for the SNR to exceed 6 dB so that there is no transmission error, while for the transmission of 5 Mb, the SNR must exceed 10 dB.
