基于Turbo码的OFDM-IDMA系统干扰消除算法
Interference Cancellation Algorithm of OFDM-IDMA Systems Based on Turbo-coded
摘要
Abstract
This paper provides a comprehensive study of interference cancellation based on Interleave-Division Multiple-Access system. Through the analysis of the structure characteristics and error correction performance of the serial interference cancellation and the parallel interference cancellation, this paper gives a combining scheme that is used for OFDM-IDMA system. By establishing equivalent channel transfer model with the conditions of Turbo Coding and OFDM technology, the combining scheme is compared with the traditional serial interference cancellation in performance. Simulation results demonstrate that the combining scheme in OFDM-IDMA system can achieve low delay on multi-user communication with less loss of error correction performance.关键词
