无线通信系统中码间干扰抑制技术研究

The Study on Suppression Techniques Against ISI of Wireless Communication System

介绍了码间干扰以及排除码间干扰的3种技术,从理论上比较了单载波频域均衡与单载波时域均衡、多载波正交频分复用技术性能,仿真结果表明:单载波频域均衡技术能显著改善均衡器、消除码间干扰的性能。

This paper describes the inter-symbol interference and three technologies for eliminating it. The performance of these technologies is analyzed in theory, make comparison between the single carrier frequency-domain equalization （SC-FDE） and single carrier time-domain equalization （SC-TDE）, multi-carrier orthogonal frequency division multiplexing （OFDM） technology, simulation results show that the single carrier frequency domain equalization （SC-FDE） technology can significantly improve equalizer erase inter-symbol interference （ISI） performance.
