摘要
为了克服在无线数据传输中,多径时延引起的码间串扰(ISI)以及白噪声对数字信号传输质量的严重影响,提出了一种判决反馈均衡器。通过详细的理论分析,MATLAB仿真以及在TMS320VC33DSP平台上的实现,分析了该方法与现今国内外一些经典教材所论述的算法在推导过程中的差异。
In order to eliminate the distortion caused by white noise and intersymbol interference in radio channels during data transmission, the application of a decision-feedback equalizer in this kind of channel is proposed. Through a detailed theoretic analysis of MATLAB simulation and realization in TMS320VC33 DSP, the difference between this algorithm and the algorithm cited in some classical teaching material is discussed.
