How to Show A OFDM Symbol
Web18 jan. 2013 · In OFDM, you map your data to represent the amplitudes of a DFT (A1,A2...). Performing the IDFT, reconstructs a time sequence that is composed of the complex exponentials (sub carriers) summed together using the amplitudes represented by the coefficients A1,A2... Alternatively, just look at the definition of the IDFT. Web按照图1,14个OFDM符号的总CP长度为(2*80+12*72)=1024。 一个时隙时长为14*1024+1024 = 15360采样点 = 1ms。 图2 1个时隙中 每个OFDM符号+CP的总长度 按照图2,从加上CP长度的OFDM符号长度也可以计算,一个时隙的时长为1104*2+1096*12=15360采样点=1ms。 图片来自《5G NR in Bullets》P106 对于CP来 … frontline developments instagram
