摘要
对脉冲体制的超宽带正交解调接收机幅相误差模型进行了深入分析。并基于冲击脉冲信号形式,提出新的正交解调接收机幅相误差分析与校正算法。弥补了现有的基于线性调频信号形式而提出的超宽带正交解调误差校正算法的不足,其更普适于各种超宽带信号形式。在实际系统中获得了理想的效果。
The error model in UWB impulse quadrature demodulation receiver has been analyzed. For impulse signals, a novel method, to analyze amplitude and phase errors, is presented. The limitation, of current method to correct errors, in UWB LFM quadrature demodulation receivers, is avoided. It＇s more suitable for many kinds of UWB signals. In the real system, a perfect result is gained.
