Der Prozess der Softwareentwicklung,Achieving IEEE 802.22 WRAN spectrum sensing specifications is challenging because of shadowing, fading, and time variation of wireless channels. These distortions can be mitigated by using diversity combining and cooperative spectrum sensing techniques. The former improves the receive SNR, and the latter mitigates the hidden terminal problem.

Introduction,In recent decades, the market for wireless devices and networks has boosted an unprecedented growth. This growth has led to numerous wireless services and applications. Consequently, regulatory agencies in different countries thus allocate (licensed) chunks of spectrum to different wireless services.

Performance Measurements,The energy detection process is affected by the fluctuations of the propagation channel, which occur due to path loss, large-scale fading and small-scale fading. Channel correlation is also a major impact when energy detectors are implemented in cooperative spectrum sensing networks .
