- Description
- In this paper coexistence and spectrum sharing
between systems as a recently critical issue due to emerging new
wireless technologies and spectrum scarcity are investigated. At
World Radiocommunication Conferences 2007 (WRC-07), International
Telecommunication Union - Radiocommunications (ITU-R) allocated
3400-3600 MHz band for the coming fourth generation (4G) or
IMT-Advanced on a co-primary basis along with existing Fixed
Wireless Access (FWA) systems. Therefore, coexistence and sharing
requirements like separation distance and frequency separation
coordination must be achieved in terms of both co-channel and
adjacent channel frequencies. Co-sited the two base stations
antennas and non co-sited coexistence of the two systems are
analyzed. The interference analysis models, Adjacent Channel
Interference Ratio (ACIR) and spectrum emission mask are applied in
the 3.5 GHz band to extract the additional isolation needed to
protect adjacent channel interference. Also interference to noise
ratio as a standard interference criteria is introduced. Finally,
possible intersystem interference mitigation techniques are
suggested and explained.
