  • Method for sensing wireless microphones using augmented spectral correlation function
    Patent number: 9214974
    Abstract: A method for detecting wireless microphone signals based on an augmented spectral correlation function is provided. The method includes obtaining an augmented spectral correlation function (SCF) of acquired digital signals based on a SCF of the digital signal and a conjugate SCF proposed in the present invention, calculating a statistic, and comparing it with a decision threshold simulated or calculated through a predetermined method to determine whether the digital signal is a wireless microphone signal. With the proposed augmented SCF, the present invention overcomes a difficulty in sensing TV white space, namely, the inability of most existing detection methods to effectively distinguish between narrowband interferences and wireless microphone signals. Meanwhile, the detection method has low algorithm complexity and is easy to implement in real systems.
