低速率无线个域网调制技术的研究
The Explore on Modulation Technique of Low-Rate Wireless
Personal Area Network
摘 要 分析了IEEE 802.15.4:2006低速率无线个域网(LR-WPAN)标准的调制方法,并提出了一种选用多相Chirp序列作为其扩频序列和采用升余弦滚降脉冲成形的调制实现方法。对比了两种不同调制方法得到的连续相位线性调频信号的特征。

Abstract: The paper analyses the modulation method of LR-WPAN standard (IEEE 802.15.4:2006) and introduces advanced modulation method using Chirp sequences and MPSK(M-ary Phase-shift Keying) modulation. The differences between the continuous phase
linear FM signal generated by these two modulation methods are particularly introduced.
Keywords: Low-Rate Wireless Personal Area Network; Chirp sequences; correlation features;impulse shape
