a finite number of distinct signals to represent digital data. PSK uses a finite number of phases, each assigned a unique pattern of binary digits. Usually, each phase encodes an equal number of bits. Each pattern of bits forms the symbol that is represented by the particular phase. The demodulator, which is designed specifically for the symbol-set bit-error-probability-for-bpsk-modulation used by the modulator, determines the phase of the received signal and maps it back to the symbol it represents, thus recovering the original data. This requires the receiver to be able to compare the phase of the received signal to a reference signal — such a system is termed coherent (and referred to as CPSK). Alternatively, instead of operating with respect to a constant reference wave, the broadcast can operate with respect to itself. Changes in phase of a single broadcast waveform can be considered the significant items. In this system, the demodulator determines the changes in the phase of the received signal rather than the phase (relative to a reference wave) itself. Since this scheme depends on the difference between successive phases, it is termed differential phase-shift keying (DPSK). DPSK can be significantly simpler to implement than ordinary PSK, since there is no need for the demodulator to have a copy of the reference signal to determine the exact phase of the received signal (it is a non-coherent s

The y-axis should probability of normally be set to use log scaling. Graph Type This measurement can be displayed on a rectangular graph or tabular grid. Computational Details The measurement generates a reference curve based on the settings of the meter block selected in the BER/SER Meter setting. Values for Pb probability of error are calculated for each value specified in the meter's SWPTV parameter. The following BPSK modulation types are supported: COHERENT BPSK: [1] where Q(x) is the Gaussian integral or Q-function: and is approximated numerically, Eb is the average bit energy and N0 is the noise power spectral density. OPTIMUM DIFFERENTIAL BPSK: [2] SUBOPTIMUM DIFFERENTIAL BPSK: [2] where the ideal narrow-band IF filter has bandwidth W=0.57/T, where T is the bit (and symbol) duration.
