Abstract
Improper spectrum allocation of technology may cause severe interference between the two technologies. The interference may cause an outage. Therefore, a minimum guard band and or a Minimum Separation Distance (MSD) are required to reduce the impact. Considering the SIR and receiver sensitivity as the reference level, a simulation is developed in this research to find the outage probability and to find the minimum guard band and or the Minimum Separation Distance between GSM and CDMA using MATLAB. The minimum separation distance between GSM Base Station and CDMA Base Station to create the outage
probability below 5% is 300 meters with 2.5 MHz guardband. For GSM MS and CDMA MS the minimum separation distance is 8 meters with 5 MHz guardband. / Pengalokasian spektrum frekuensi antar teknologi yang kurang tepat dapat
menyebabkan interferensi. Hasil kurang tepatnya pemisahan frekuensi tersebut
menyebabkan beberapa hal seperti putusnya hubungan telepon atau berkurangnya
data yang didapat. Oleh karena itu, batas minimum guard band atau jarak
minimum (MSD) antar alat komunikasi diperlukan untuk mengurangi interferensi.
Dengan memperhitungkan beberapa aspek seperti SIR (Signal-to-Noise Ratio) dan
sensitivitas receiver sebagai referensi untuk membuat simulasi untuk mengetahui
batas minimum guard band dan batas minimum jarak antar teknologi dengan
menggunakan Matlab. Jarak pisah minimum (MSD) antara BS GSM dan BS
CDMA agar interferensi yang terjadi tidak menghasilkan probabilitas outage lebih
dari 5% adalah 300 meter dengan guardband sebesar 2.5 MHz. Sedangkan untuk
jarak pisah minimum antara MS GSM dan MS CDMA adalah 8 meter dengan
guardband sebesar 5 MHz.
