Abstract
For a cellular system, the system throughput as well as the throughput at a cell edge are among the most important evaluation measures for the requirements on the system performance. Several inter-cell interference mitigation techniques have been proposed to meet the cell-edge users' needs in downlink. Each interference mitigation scheme has been found that they have pros and cons at the same time. In this paper, an adaptive inter-cell interference management scheme is proposed for an LDPC-coded FH-OFDMA system to combat the inter-cell interference in downlink cellular environment. Based on the knowledge on other cells that we can utilize without dynamic cooperation between cells, different decoding methods can be applied to maximize the performance for the cell-edge users. It is shown that a significant gain can be obtained, especially at the cell boundary using the proposed scheme.
