摘要

针对单载波分组传输系统中信道的频率和时间选择性，提出了迭代分组决策反馈均衡器。该算法采用环形前馈和反馈滤波器来对抗符号间和载波间的干扰，同时降低了计算复杂度。仿真结果验证了该算法的有效性。

Iterative Block DFE for Doubly Selective Fading Channels

We present the iterative block decision-feedback equalizer aimed at overcoming channel’s frequency and time selectivity in single-carrier block transmission systems.The algorithm features circularly banded feedforward and feedback filters to combat the inter-symbol and inter-carrier interference, while achieving a reduced computational complexity. Simulation results demonstrate the efficacy of the algorithm.

期刊介绍： The IEEE Communications Letters publishes short papers in a rapid publication cycle on advances in the state-of-the-art of communication over different media and channels including wire, underground, waveguide, optical fiber, and storage channels. Both theoretical contributions (including new techniques, concepts, and analyses) and practical contributions (including system experiments and prototypes, and new applications) are encouraged. This journal focuses on the physical layer and the link layer of communication systems.
