In this letter, an efficient detection scheme is proposed to mitigate the effect of the carrier frequency offset (CFO) in spatial modulation orthogonal frequency division multiplexing (SM-OFDM) systems. Specifically, the proposed scheme employs a novel symbol-by-symbol-aided iterative detector to the SM-OFDM systems with multiple CFOs, where the zero symbols are considered as constellation points...
In this paper, a improved low-complexity scheme is presented to compensate the multiple carrier frequency offsets (CFOs) in the uplink of interleaved orthogonal frequency division multiple access (OFDMA) systems. Based on the assumption that multiple CFOs is modeled as Gaussian variables [11][12], all the users are divided into two different sets, defined as large CFO users set (LCUS) and small CFO...
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...
