摘要：
A general method for constructing nonnegative-definite, joint time-frequency distributions (TFD's) satisfying the marginals of time \s(t)\(2) and frequency \S(f)\(2) is presented. As nonnegative-definite distributions with the correct marginals, these TFD's are members of the Cohen-Posch class. Several examples illustrating properties of these TFD's are presented for both synthetic and real signals.
