Nowadays, the demand of spectrum is rapidly increasing since the quality of communication has significantly been focused on by users. Therefore, as a research point of next generation network (NGN), integrated satellite-terrestrial network has been considered by institutions and universities. The most significant advantage of an integrated satellite-terrestrial network is taking full advantage of existing inadequate spectrum resources. In such network, the terrestrial system uses the same portions of frequency bands as an associated operational satellite system. This chapter intends to model and analyze several frequency sharing schemes in integrated satellite-terrestrial network with the analysis of unavoidable interference caused by frequency sharing and finally find the preferred solution.
