摘要 chirp-rate调制是线性调频扩谱通信的一种调制样式,具有很强的抗多径和抗多普勒频移能力。为进一步提升chirp-rate调制码元传输的带宽利用效率,提出了一种码元宽度部分重叠的chirp-rate调制高效传输方法。然后,推导了其带宽效率提高倍数。接下来,基于分数阶Fourier域解调而推导了单个码元宽度内不同调制信号的分数阶傅里叶谱对正确解调的影响,并据此导出了部分重叠传输模式下的带宽效率提高倍数最大值的解析表达。最后,通过仿真分析验证了上述理论推导的正确性。 width. The improving coefficient of bandwidth efficiency is derived. And then the influence over correct demod- ulation is analyzed using the demodulation method in the fractional Fourier domain, which comes from the re- spective fractional Fourier spectrum of each different modulated signal within single code width. Further, the analytic expression of improving maximum of bandwidth efficiency is obtained in the transmission pattern of par- tial overlap. Finally, the above-mentioned theories are proved through simulation. Key words： spread spectrum communication; chirp-rate modulation; code transmission;bandwidth efficiency
