Receiving of the broadband phase modulated signal with quadrature phase-shift keying in case of multiple access in-terference and internal Gaussian noise has been considered. Bit error rate of broadband phase modulated signal with quadrature phase-shift keying has been obtained in case amplitudes of receiving signal and interferences have both regu-lar and fluctuating components. Broadband phase modulated signal bit error rate as a function of signal-to-noise ratio, signal-to-interference ratio, number of interferences and false positive probability has been analyzed.
