By using the quantum field theory in curves space-time, Steven Hawking showed that a black hole can be radiant. This radiation is called Hawking radiation, and it takes up approximately a form of thermal radiation. Since thermal radiation is not correlated, the thermal description of the black hole radiation suggests that all information about the body that collapses into the black hole will be disappeared. Several methods have been proposed for describing the black hole radiation to provide a non-thermal description of the black hole’s radiation spectrum. One of these methods for measuring the black hole radiation spectrum is Parich- Wilczek method. Initially, we introduce the Parikh-Wilczeik method for describing the black hole radiation and determine the probability of particles radiation from different black holes. After that, we will examine the effect of generalized uncertainty in the Perich-Wilczek method. And then, by counting the number of black hole micro states according to the number of radiation microstates, we obtain the entropy of the black hole. Finally, in the Parikh-Wilczeik proposal we model the black hole as a Markov process, and we study the properties of radiation.
