Performance Analysis for System Co-existence between Adjacent Channels with Extended Hata and IEEE 802.11in TVWS

In this paper, we analyze the maximum allowable transmitting output level of transmitter, which meets the required interference probability, in order to get the method that different communication systems can be existed and used simultaneously in adjacent channels. We analyze the performance result according to various density of interfering transmitter and transmitter output in hetero systems. In order to get the relationship with between density of interfering transmitter and transmitter output, we consider WiBro as an interfering transmitter, WLAN as a victim receiver and Extended Hata and IEEE 802.11 model as a channel environment respectively. Analyzed coexistence results may be widely applied into the technique developed to get the coexisting condition for wireless devices using many communication protocols in same frequency.
