Stochastic Description of Wireless Channel for Cognitive Radio
Original language description
The common description of wireless propagation channel is frequency dependence of the attenuation, which is not appropriate parameter for modern communication systems using micro cells. It is more required to have information about utilization and interference in the particular channels, because there is no diffculty to set up link budget for small cell wireless transmission. This paper introduces innovative stochastic channel description mainly for cognitive radio application. Based on the localization of the primary users in the frequency spectrum at current location, cognitive system minimizes risk of the interference between primary and cognitive users using dynamic spectrum sharing. Hence we are presenting suitable model of spectrum occupancy for cognitive system based on stochastic analyses. According to the typical utilization of the wireless channel it is possible to classify typical radio transmission according to several criteria as following: utilization of the specific frequency band, bandwidth of the unused part of spectrum, duration of the spectral holes in the frequency band. These parameters should be used for wireless service planning rather than conventional one. Subsequently, we can reach more reliable results.
