The unlicensed users utilize a frequency band with the licensed no adverse interference on licensee, this can be achieved by cognitive radio (CR) technique. This study examines how effectively underlay CR transmission improves spectrum efficiency. We specifically calculated generalized area spectral efficiency (GASE) parameter assessment and design of transmission. ergodic capacity primary secondary in over Rician fading channel was initially described closed-form expressions. Further, GASE performance is examined mathematically relation to restriction receiver. Finally, all MATLAB simulations are exactly intact theoretical analysis.
