Abstract
In traditional CDMA networks, transmit power control (TPC) is main technology to mitigate interference of cell-edge users (CEU), and in 4G-LTE networks with OFDM, fractional frequency reuse (FFR) for CEU is main technology for its flexibility of subcarrier pre-coding. In this paper, we propose a FFR scheme based on cell-edge interference alignment (IA) in DCF infrastructure networks first, then present a performance analysis and compare it with TPC by using probability theory with same node density based on BM model, simulation are given at last. Results show that TPC and soft FFR are almost same in terms of average throughput, former has a little more outage or error probability; TPC with upload and download in different channel has the best throughput performance.
