Abstract:
Radio spectrum’s sharing guideline is an essential component of spectrum
utilization process. Since there is no insightful interference avoidance method in
a radio system, the careful selection of sharing conditions is the only means for
achieving successful co-existence and optimal spectrum usage in the radio
system. Spectrum sharing rule can be obtained by an analytical method or
statistical method. The analytical method considers the worst case scenario to
calculate sharing rules. Nonetheless, this doesn’t represent the lasting
phenomenon amid ordinary task; moreover sharing rules may be unnecessarily
rigid. Henceforth, the Monte Carlo Simulation (MCS) strategy has been utilized
to establish a probability of interference based on a random distribution of victim
link receiver in time and space with respect to victim link transmitters.
The study has been done for cluster number N with values of 1, 3, 4, and 7 in a
cellular system. Monte Carlo Simulation analysis showed the percentages of
interference are 24.94%, 9.36%, 3.33%, and 0.4% for N ¼ 1, N ¼ 3, N ¼ 4, and
N ¼ 7 respectively. In terms of throughput per total bandwidth per a single site,
N ¼ 7 offers a spectrum utilization of 1/7 and N ¼ 4 offers a spectrum utilization of 1/4. Therefore, a relative enhancement in capacity of 7/4 has been
achieved with 3.3% probability of interference which is below the threshold
value of 5%.
