Applying the method of Parikh et al., we study the Hawking radiation of a Kerr-Newman-de Sitter (KNdS) black hole as a tunneling process. Higher-order corrections to the emission rate exist and the corrected radiation spectrum deviates from the precisely thermal spectrum. The result is consistent with an underlying unitary theory and compatible with the results obtained earlier.
