Two major challenges for evolving LTE (Long Term Evolution) networks are to achieve enhanced
system capacity and cell coverage compared with WCDMA (Wideband Code Division Multiple Access)
system. Effective utilization of radio resources as well as dense spectrum reuse are at the core to attain
these targets. However, dense frequency reuse may increase inter-cell interference, which in turn
severely limits the capacity of users in the system. Inter-cell interference can restrict overall system
performance in terms of throughput and spectral efficiency, especially for the users located at the cell
edge area. Hence, careful management of inter-cell interferences becomes crucial to improve LTE
system performance. In this paper, interference mitigation schemes for LTE downlink networks are
investigated |
