| 摘 要： | 提出了在并行组合采样系统这种多通道组合采样系统中,对于时基非同步信号,使用插值算法对组合信号进行重构的方法。实际的并行组合采样中,由于各采样通道之间的采样时钟相位控制存在时基偏差,引起了采样信号的时间非同步,导致采样波形非线性失真。为补偿系统的无杂散动态范围和实际信噪比,有效地还原信号原貌,需要对采样序列进行信号重构。提出了用插值算法来重构信号,实现对时基偏差的校正,并通过仿真验证,分析了此方法的可行性。

| Abstract: | In the multichannel combined between channels. Interpolation is used for sampling system, the time base usually has a little difference compensation. In a practical combined sampling system, clock phase control between multi-channels has a time base difference, bringing in the asynchronous sampling signals, that is non-linear distortion. A method of signal reconstruction is proposed for error adjustment. It is simulated and validated for its feasibility. |
