| 摘 要： | 单边带调制是用软件无线电中的主要调制方式之一，由于数字信号处理芯片与专用数字芯片的发展，需要对各种信号的调制的数字化实现进行研究，从单边带的数学表达式出发，推出了复数域的单边带数学表达式，从而提出基于复数滤波的单边带调制方法，计算机模拟与实际测试显示，该法性能良好，运算量小，具有很高的实用价值。

| Abstract: | Single sideband amplitude modulation is the major model of the military software radio. Because of the development of the digital signal-processing chip, digital realization of modulations needs to be researched.Complex expression of SSB is deduced and the algorithm of complex filtering is put forward. The method of shift-phase takes place of the method of filtering. Calculations analysis, computer simulation and practice test show that the method has good performance. |
