Shot Interference Detection and Mitigation for Heterogeneous Networks

A chance constrained approach for uplink wireless OFDMA networks

“…Wireless Networks (WNs) have become an active research field within the last decades [8]- [14]. Although they have remarkably improved, by performing a slight revision of related literature, it is easy to observe that more intelligent and powerful mobile equipments will be required to meet users increasing demands in the near future.…”

“…Among them, wireless OFDMA networks appear as one of the most interesting candidates as they use OFDM technology which divides the frequency bandwidth channel into several orthogonal subcarriers (or sub-channels) with an increased robustness to overcome multi-path distortions. In order to efficiently assign the bandwidth channel capacity and power in OFDMA networks, several approaches have been proposed in the literature so far [8]- [14]. Some efforts have been made by taking into account the stochastic nature of the problem [9], [13].…”

ESPS scheme for two‐tier interference suppression in a heterogeneous network with cooperative femtocells

“…In order to suppress these interferences, we propose a precoding scheme in a heterogeneous network with cooperative femtocells, called CotIN elimination and CrotIN suppression with precoding criterion selection (ESPS) scheme. The authors in [19][20][21][22] presented schemes to reduce the CrotINs from femtocells to MUs or from the macrocell base station to FUs. Then the CrotINs of macrocell users and femtocell users are suppressed via the macrocell base station (MBS) and femtocell access points (FAPs) with precoding criterion selection, respectively.…”

“…The schemes in [17,18] were introduced for the CotIN suppression. The authors in [19][20][21][22] presented schemes to reduce the CrotINs from femtocells to MUs or from the macrocell base station to FUs. Furthermore, Park et al [23], Park et al[24], and Dai et al[25] adopted different schemes for suppressing both the types of CrotINs.…”
