So far, the transmission rate of digital communication has approached the theoretical upper limit proposed by Shannon 70 years ago, and the academia and industry circles are puzzled by the lack of new theories to point out the direction of further increasing the transmission rate. In this paper, the completeness of Shannon channel capacity equation is analyzed in the framework of signal uncertainty principle, which brings the Shannon theory a more solid physical theoretical basis. Then the theoretical method of breaking through the Shannon Limit is proposed. Finally, it is proved that the time-shifted non-orthogonal multi-carrier digital modulation technology which we have studied for more than 20 years is a practical method to break through the Shannon Limit.
