Description: . 对于基于块状(block-type)导频的信道估计,仿真实现LS, LMMSE modified 和基于SVD的降维LMMSE 算法在多径频率选择性特征的信道上的BER VS SNR 和BER VS Doppler frequency shift 的功能。
2. 对于基于梳状(comb-type)导频的信道估计,实现LS with 1D linear interpolation, LS with second-order interpolation, LS with Spline cubic interpolation.
3. 比较块状和梳妆导频信道估计方法在不同的特征的信道上的性能(channel with fast fading and channel with slow fading).
4. 信号的调制方式可以选择16QAM或者QPSK
5.对于SVD-LMMSE (optimal rank reduction), rank的取值P也会的到分析。
