In this paper, the authors have proposed a multiuser Space frequency (SF) code with high symbol rate and full-diversity. This SF code is constructed from a threaded algebraic layering concept. It combines the space-frequency layering concept with algebraic component codes where each component code is assigned to a “thread” and interleaved over space and frequency. It is proved...
In orthogonal frequency division multiplexing (OFDM) system, the frequency offset in mobile radio channel leads to the loss of sub-carrier orthogonality which causes inter-carrier interference (ICI). As a result, the performance of the system will degrade. The authors have proposed an efficient scheme for ICI cancellation. Simulation results show that the proposed scheme outperforms the conventional...
