Nitrogen Vacancy (NV) centers in diamond have been seeing increasing attention in applications of quantum theory and especially in quantum information processing. To understand the effects of the diamond lattice on the NV center, we analyze the noise due to the nuclear spins of the Carbon 13 atoms (that's about 1% of the Carbon atoms in the lattice) in the diamond lattice using the phenomenon of Coherent Population Trapping and then we find the optimum dynamical decoupling pulse sequence that prolongs the decoherence of a computational qubit made out of the nuclear spin degree of freedom of the Nitrogen 15 atom in the NV center.
