Reducing Interference by Planning HSN Pairs
The hopping sequence number (HSN) is the parameter that differentiates the hopping algorithm between two cells having the same MAList. There exist 64 possible HSNs (0 is cyclic and 1 to 63 random). The principle of SFH (spreading of interference) is assured via the HSN. Two cells having the same MAList and different HSNs hop differently; they may at a single moment use the same frequency, but shortly after those two cells will camp on different frequencies. In the case of the 1 / 1 model, since all three sectors use the same MAList, three different HSNs should be attributed per site, whereas with the 1/ 3 model the same HSN can be used for all cells with the condition that sectors are synchronized. Some simulation results have shown that according to the hopping algorithm, behind each HSN value some pairs of HSNs produce a higher probability of interference than others. Table 1 and Table 2 give the probability values for the best and worst performing pairs of the HSN. Table 1 Worst Pair of HSN HSN Site1

We can find that the collision probability of worst pair of HSN is almost twice of that of best pair. We have tested these values in a project using Unet and we have achieved better results by avoiding the worst pairs and using the best pairs of HSN. Table 2 Best Pair of HSN HSN Site1
