An efficient approach for instantaneous frequency (IF) rate estimation is proposed. It is based on a timefrequency rate representation with complex-lag argument. The proposed representation is derived in a manner to reduce the spread factor, and thus to provide high concentration along the IF rate. Due to the significantly reduced spread factor, it is suitable for periodically frequency modulated signals whose phase vary fast even within a few samples. The theory is proven by the example.
