Interference originates in WRAN could cause DTV service outage. In this paper, the uncertainty in prediction is measured by outage probability, $$P_{o}$$ . With spectrum sensing capability, WRAN can avoid operating in the TV band where DTV signal is detected to be present. Nevertheless, due to limited sensing accuracy, interfering operation cannot be completely avoided. Cooperative spectrum sensing (CSS) gives better detection by means of combining multiple sensing results. This paper investigates the extent of which $$P_{o}$$ is reduced as a result of implementing CSS in WRAN. The investigation is conducted for two different combining techniques: Equal Gain Combining and Selection Combining, and four different types of channel variability: Gaussian, Nakagami, Rayleigh, and Rician channels. All theoretical results have been validated by Monte Carlo simulations. An arbitrarily chosen example shows that $$P_{o}$$ reduces by about 40 times after implementing CSS.
