Abstract


In order to support the growing number of mobile users and satisfy their quest for more broadband mobile services, additional spectrum needs to be allocated to the International Mobile Telecommunication (IMT), which is the international standard for mobile communication. However, the radio spectrum being a natural resource cannot be manufactured or reproduced. At the moment there is no empty spectrum to allocate to IMT. This is why the International Telecommunication Union (ITU), plans to enable IMT to share some frequency bands with other existing radio services. One of such bands is 3300 – 3400 MHz, which is currently being used by radiolocation services in all parts of the world on a primary basis. For co-existence in this band to be possible, it is required that IMT services and radiolocation services should not to cause harmful co-channel interference to each other. This work used Spectrum Engineering Advanced Monte Carlo Analysis Tool (SEAMCAT) to study the interference scenario to determine the probability of interference from IMT-Advanced base station to ship-based C radar. The results show that in 85% of the time, IMT-Advanced systems will harmfully interfere with the ship-based radar system. This means that IMT-Advanced base station and ship-based radar C cannot share 3300 – 3400 MHz band without application of interference mitigation technique.
