线性正则变换域带宽有限随机信号的非均匀采样
Nonuniform Sampling for Random Signals Bandlimited in the Linear Canonical Transform Domain
本文主要研究线性正则变换（LCT）域带宽有限随机信号的非均匀采样,证明经过 LCT 域预滤波,LCT 域带宽有限随机信号的非均匀采样与均匀采样具有相同的二阶统计量,并进一步给出从 LCT 域带宽有限随机信号的非均匀采样近似重构原始信号的方法。此外,本文还给出非均匀采样的均方误差估计。
he nonuniform sampling for random signals which are bandlimited in the linear canonical transform (LCT) domain is studied in this paper.It was shown that the nonuniform sampling for a random signal bandlimited in the LCT domainis equal to the uniform sampling in the sense of second order statistic characters after a pre-filter in the LCTdomain. Moreover, an approximate recovery approach for nonuniform sampling of random signals bandlimited in the LCT domain is proposed.Finally, the mean square error of the nonuniform sampling is studied.
