摘要
甚小线性调频键控(VMCK)是一种高效的超窄带调制技术,具有窄带占用,强边带抑制,数据传输效率高等优点。频分复用技术是一种常用的提高频带利用率手段,在超窄带的通信结构基础上,根据VMCK调制原理,利用Simulink搭建超窄带系统的四路信号复用系统,并进行分析。
VMCK (Very Minimum Chirp Keying, VMCK) is a highly efficient ultra narrow band modulation techniques with narrow footprint, strong sideband suppression, data transmission efficiency. Frequency division multiplexing is a commonly used, means of improving bandwidth efficiency. In the uhra-narrow band communication structure based on the modulation principle VMCK, the multi-band ultra-narrowband system four signal multiplexing system are built and analyzed.
