The paper presents theoretical analysis of CI/PO-CI/OFDM technique at different sampling rates, and proves that CI/PO-CI/OFDM signal can be obtained by simple rearrangement of the parallel data with or without phase rotation and can be regarded as cyclic-prefix-based single carrier (SC-CP) system but with much more complexity at both the transmitter ...

Orthogonal frequency division multiplexing (OFDM) is a high efficient multi-carrier modulation technique for the new generation cellular networks, which is sensitive to frequency offset. In this paper, we focus on the performances of anti-frequency offset in the time shifted non-orthogonal frequency division multiplexing (TS-NFDM) and OFDM systems ...

Interference mitigation in orthogonal frequency division multiplexing (OFDM)
Proceedings of ICUPC - 5th International Conference on Universal Personal Communications, 2002Orthogonal frequency division multiplexing (OFDM) is a modulation scheme purported to be insensitive to the multipath effects of a mobile communication channel as well as exhibiting immunity to narrow-band interference via hole punching in the OFDM spectrum.
