中文摘要	提出了一种可以用于信道或传输设备测试的实地信道数据准实时测量及回放系统。利用叠加高斯白噪声的线性时变等效基带信道模型来描述信道;通过仔细选取训练序列以及设计相应的算法可以高效地进行信道测量。与传统的信道测量与回放方法相比,该系统具有复杂度低、可重复性好和实时采集等优点。; In this paper, a new quasi-real-time field channel sounding and simulating system is propsed.This system could be used for communication channel and equipment test.The channel to be measured is modeled as equivalent baseband Linear-TimeVariant channel with additive Gaussian white noise.Through the careful selection of training sequences and corresponding channel estimation algorithm, channel parameters can be precisely and effectively estimated with low-cost computations.Compared with ex-isting methods, the proposed scheme is advantageous due to reusability, real-time measuring, low complexity and universality.
