It has been proved to have advantages in some parameter estimation issues over conventional modulation schemes. In this paper, a novel transform termed as Discrete Sinusoidal Frequency Modulation transform (DSFMT) is proposed. Then, the DSFMT of SNCK signal is deduced and classified into three types, based on which, the time-bandwidth product is estimated by the proposed algorithm. Simulation results show that the noise has a significant impact on the localization of the peak value and the time-bandwidth product can be estimated by using local ratio values when SNR≥5db. %U http://www.cic-chinacommunications.cn/EN/abstract/article_567.shtml
