Cooperative Spectrum Sensing Based on Softened Two-Bit Hard Combination Scheme

This paper measures the performance of cooperative spectrum sensing, over Rayleigh fading
\nchannel and additive white Gaussian noise, based on softened two-bit hard combination scheme. Two
\nmeasures based on energy detection are considered including effect of false alarm probability, and effect
\nof number of users. Simulation results show that the detection probability increases with the increase
\nof false alarm probability, number of users, and signal-to-noise-ratio
