本又提出利用声表面波(SWA)滤波器在载波上直接实现符号成形与调制。用切尾余弦系列作为基函数在连续相位,恒包络及附加谱分布字条件下对成形符号函数进行设计,并提出一种新的采样重构法优化设计此SAW调制滤波器,最后给出模拟结果并得出结论。
This paper also proposed the use of surface acoustic wave (SWA) filter on the carrier directly to achieve symbol shaping and modulation. The tangential cosine series is used as the basis function to design the shape function under the condition of continuous phase, constant envelope and additional spectrum distribution. A new sampling and reconstruction method is proposed to optimize the SAW modulation filter. Finally, Simulation results and draw conclusions.
