Description: 频域不同导频密度的信道估计在被研究，并且在高低时延信道其信道估计被固定了导频分配时域。频域信道估计是基于插补，多项式的广义线性模型（或最小二乘法）和维纳滤波（或线性最小均方误差法）的方法。时域的信道估计是用线性插补完成的。我们通过测量在基于克拉克散射模型的瑞利衰落信道上并带有QPSK调制的粗误码率，已经比较了所有这些方案的结果。-Different pilot density in frequency domain channel estimate to research, and its high and low delay channel estimation channel was fixed allocation of time-domain pilot. Frequency domain channel estimation is based on interpolation, polynomial generalized linear model (or least squares) and the Wiener filter (or linear minimum mean square error method) method. Time domain channel estimation is done using linear interpolation. We are by measuring the scattering model based on Clark and Rayleigh fading channels with QPSK modulation bit error rate of crude, has compared the results of all these programs. Platform: |
