Abstract A cone-kernel time-frequency representation using adaptive scheme over both time and frequency is presented. For adapting to the analysed signal, the time-frequency representation uses varying cone length in each time-frequency point. It yields better results and requires only slightly more computation than the cone-kernel time-frequency representation that uses only time adaptive scheme.
