| ABSTRACT |
In this approach, a new schemes for an optimum fixed relay node (FRN) location in a LTE-A cellular network to enhance coverage and throughput at cell edge. The proposed approach mitigates interferences between all nodes and ensures optimum utilization with the optimization of transmitted power. Moreover, the optimal number of relays to provide the best coverage and power allocation at the lowest cost has been derived. Simulation results indicate an improvement in capacity for users at the cell edge from 0.6 b/s/Hz to 1.45 b/s/Hz and 40% increment from all cell capacity. Moreiver, a gain about 8 dBm and 25 dBm is observed for users at the cell edge for uplink and downlink in the received signal respectively. It has been concluded from the numerical analysis which is conducted on limited interferences for all nodes (in-band and out-band) provides simplicity and ease in implementation by the RF planning designers. These numerical analysis are verified by ATDI simulator which based on a real digital cartographic representation of an urban area that is approximately 176.7 Km.
