Abstract
In this paper, we consider an FH-OFDMA system with LDPC codes for the downlink of cellular systems to realize the frequency reuse factor of one. For the system, we propose simple erasure detection and LDPC decoding methods to effectively combat the highly non-uniform interference caused by the different power allocation to the data channels and frequency hopping in adjacent cells. With the proposed methods, the performance is remarkably improved in partially interfered cases without severe performance loss in uniformly interfered cases.
