Cyclic Prefix Adaptation with Constant Overall Symbol Time for DFT-spread-OFDM and OFDM

Liangping Ma, Tao Deng, Alpaslan Demir

For DFT-spread-OFDM or OFDM, if the delay spread varies in a wide range and the symbol duration is relatively short, adapting the cyclic prefix (CP) duration rather than using a fi…
