Bpsk Probability Of Error Derivation
Type List of options N/A Result The measurement plots a theoretical QPSK bit or symbol error probability along ber for qpsk matlab code the y-axis and the swept variable (typically Eb/N0 or Es/N0) along the x-axis. The y-axis should normally be set to use log scaling. Graph Type This measurement can be displayed on symbol error rate a rectangular graph or tabular grid. Computational Details The measurement generates a reference curve based on the type and settings of the meter block selected in the BER/SER Meter setting. If the Statistic Type parameter is set to Auto, the measurement will compute the bit error probabilities Pb for BER meters and symbol error probabilities Ps for SER meters. Values for

Pb or Ps are calculated for each power value specified in the meter's SWPTV parameter. For QPSK, the symbol error probability is related to the bit error probability by [1]: Ps=2Pb-Pb2 The following QPSK modulation types are supported: COHERENT QPSK: [1] where Q(x) is the Gaussian integral or Q-function: and is approximated numerically. Eb is the average bit energy, Es is the average symbol energy and N0 is the noise power spectral density. OPTIMUM DIFFERENTIAL QPSK: [2] The measurement approximates optimum differential QPSK as: SUBOPTIMUM DIFFERENTIAL QPSK: [3] The measurement approximates suboptimum differential QPSK as: COHERENT DIFFERENTIAL QPSK: [4] The measurement approximates coherent differential QPSK as: which is applicable at high SNR.
