1.
In order to enhance channel estimation performance of NC-OFDM systems in the case of lacking enough pilot symbols,a novel channel estimation scheme with modified noise reduction in transform domain is proposed.
针对NC-OFDM系统在某些相干带宽内可能没有足够的导引符号,导致基于频域内插的LS信道估计算法性能较差的问题,提出了一种修正变换域降噪的信道估计算法。
4) wavelet transform/restrain noise
小波变换/去噪
