摘　　要：本文在分析了常规的单边带调制/解调方法的弱点之后,提出了一套基于复信号滤波和数字信号内插/抽取原理的单边带调制/解调新方法。该方法不仅有助于减小单边带调制/解调过程中的信号失真,而且便于采用数字信号处理方法实现。计算机仿真和DSP实现的结果表明,该方法具有推广应用的价值。After analyzing the conventional methods of single side-band modulation/demodulation, this paper proposes a set of new methods based on complex signal filtering and digital signal interpolation/decimation. The new method is not only helpful in reducing the distortion of the output signals, but also convenient to implement with digital signal processing algorithms. The result of computer simulation and DSP implementation show that it is useful and applicable.
