Summary: | In Heterogeneous Network (HetNet), the
femtocell (HeNB) has been deployed by the telecommunication
industries to provide extensive coverage as well as capacity in
an indoor. These HeNBs are Customer Premise Equipment
(CPE) which is randomly used in co-channel with macrocell
(MeNB) and causes the Co-Tier Interference (CTI) in OFDMA.
The effect of CTI in OFDMA systems can lead the system
throughput degradation and service disruption. Because of
quick direct changing features in Rayleigh channel, it is
compulsory to succeed the satisfactory performance. The
signal-to-interference noise ratio (SINR) is arbitrary which
drives the highest capacity to be an irregular variable.
However, this paper derives the expressions of outage
probabilities based on the hybrid Genetic Algorithm (GA) with
biogeography based dynamic subcarrier allocation
(HGBBDSA) algorithm is implemented in reducing the outage
probability. The outage probability countenance is expressed
for the moment-generating function of the total SINR at the
receivers end. The simulation results demonstrate that the
HGBBDSA can lessen the outage to 45 % than existing
methods. |
