Interference studies between IMT-Advanced and fixed satellite service
The International Telecommunication Union (ITU) in world Radiocommunication conference (WRC-07) meeting recommended the IMT-Advanced to operate in the range of 3.4- 3.6 GHz to achieve high bit rate and large bandwidth. However, this band is used for fixed satellite service (FSS). Accordingly, differ...

| Summary: | The International Telecommunication Union (ITU) in world Radiocommunication conference (WRC-07) meeting recommended the IMT-Advanced to operate in the range of 3.4- 3.6 GHz to achieve high bit rate and large bandwidth. However, this band is used for fixed satellite service (FSS). Accordingly, different types of interference like Co-Channel Interference and Adjacent Channel Interference is faced by FSS. In this project, testing the compatibility between the International Mobile Telecommunication (IMT-Advanced) and Fixed Satellite Service (FSS) networks in range 3.4-3.6 GHz (C-band) has been studied and discussed in details. Possibility of coexistence and sharing analysis were obtained by taking into account the detailed calculations of most useful formulas for path loss effect and clutter loss by using the existing parameters of FSS and IMT-Advanced. In-band interference has been concluded, analyzed and simulated by using MATLAB for several environments in response to different clutter altitude. MATLAB also used to find out the required interference threshold for FSS and required separation distance based on in and out of band and saturation interference. Moreover, different techniques are investigated in order to study the Co-Channel Interference as well as Adjacent Channel Interference. Furthermore, the results indicated that the proposed mitigation scheme is highly efficient in terms of reducing the separation distances. |
