触屏网络中基于多载波机制的短帧的研究

Research on Short Frame Length Based on Multi- carrier( MC) Scheme in Tactile Internet

触屏网络(Tactile Internet)作为5G最新提出来的一种研究领域,它可以实现人与物体、物体与物体通信时发送端到接收端的时延接近1 ms。比较了具有竞争力的3种波形:OFDM、FBMC和UFMC多载波波形,基于UFBM波形,通过帧长度优化设计出一种最适合的短帧长度,在人与物体、物体与物体通信时减少端到端往返时延。通过matlab仿真,可以得到一个帧长等于0.2 ms的短帧,同时也保证了系统效率。

The tactile Internet has been recently proposed as a promising technology,and it can improve the transmission delay from transmitting end to receiving end close to 1ms in communications between objects as well as between human and objects. This paper compared such three waveforms as OFDM,（ Filter Bank Multi- carrier）,UFMC（ Universal Filtered Multi- carrier）. Based on UFBM waveform,an optimal short frame is designed with frame length optimization,which can shorten the end- to- end delay in communications between objects as well as between human and objects. By simulation,a short frame in length of 0. 2ms can be obtained without system efficiency reduction.
