OFDM-IM, which uses the indices of active subcarriers to carry additional information bits, is a novel multi-carrier transmission technique. In this letter, by exploiting the special design of OFDM-IM, we propose an analytical approach to evaluate the error probability of OFDM-IM subject to carrier frequency offset (CFO) in fading channels, where the inter-carrier interference (ICI) is properly divided...
For the uplink interleaved single carrier frequency division multiple access (SC-FDMA) system, one of the main problems is that the multiple carrier frequency offsets (CFO), caused by Doppler shift in high-speed wireless communications, will cause severe inter-subcarrier interference (ICI), so as to influence the system performance. In this paper, we propose an effective multiple CFO compensation...
Single carrier frequency division multiple access (SC-FDMA), which combines single carrier modulation with frequency domain equalization, is a promising transmission technique in 3GPP LTE. In this paper, for SC-FDMA signals, the issue of multiuser interference (MUI) suppression is investigated in interleaved FDMA (IFDMA) system. Under this system, carrier frequency offset (CFO) underlines the orthogonality...
