Spectrum sharing of the international mobile telecommunication-advanced and digital broadcasting in the digital dividend band

Increasing demand for wireless services has recently led to a radio spectrum shortage. As the spectrum is a limited and scarce natural resource, it should be used as efficiently as possible. In this thesis, a spectrum sharing study is conducted between the Digital Broadcasting (DB) and International...

As the spectrum is a limited and scarce natural resource, it should be used as efficiently as possible. In this thesis, a spectrum sharing study is conducted between the Digital Broadcasting (DB) and International Mobile Telecommunication-Advanced (IMT-A) in the 470–862 MHz band.

From this, it is seen that when the DB bandwidth is 8 MHz, a higher IMT-A bandwidth (20 MHz) can co-exist more feasibly with DB than a lower IMT-A (5 MHz) bandwidth.
