Polynomials, including relationships involving the roots of quadratic and cubic equations, the remainder theorem.
Based on the remainder theorem and direct dechirp operation, an algorithm for estimation of chirp rate and initial frequency of the subsampling wideband LFM signal unambiguously is presented.
Using the theorem of linear Diophantine equations and the Chinese remainder theorem, we have constructed a class of trap-door knapsack public-key cryptosystems, which have a better security.
