Abstract

This paper focuses on the cleaning of radio channel measurements using interference suppression (IS) methods. The investigated radio channel was measured in a sub-urban environment at 2.45 GHz with 200 MHz bandwidth. The measurements contain badly corrupted data, where the wideband measurement signal coexists with several "narrowband" (ca. 10-20 MHz) interfering signals. Interference suppression was performed using the backward consecutive mean excision (CME), forward CME (FCME) and limiter CME (LCME) algorithms. The performance of the CME algorithms was of interest. The results verify that it is possible to clean the corrupted channel measurement data with reasonable computational costs

2.45 GHZ无线信道测量数据的干扰抑制

本文主要研究利用干扰抑制(IS)方法对无线电信道测量结果进行清洗。所研究的无线电信道是在城郊环境下测量的，频率为2.45 GHz，带宽为200 MHz。测量包含严重损坏的数据，其中宽带测量信号与几个“窄带”(约10-20 MHz)干扰信号共存。干扰抑制采用后向连续平均切除(CME)、前向连续平均切除(FCME)和限幅连续平均切除(LCME)算法。CME算法的性能令人感兴趣。结果表明，在合理的计算成本下，清除损坏的信道测量数据是可能的
