Abstract :
Due to the time variation and frequency offset of mobile radio channels of the OFDM system, the orthogonality between sub-carriers will be destroyed. In this paper, a novel phase rotation technique is proposed in MISO OFDM system, which can suppress the inter-carrier interference (ICI) efficiently. This new method can get the minimum of sub-carrier interference in frequency domain by rotating the phase properly on different transmit antenna at each sub-carrier. Simulation results are given to show the performance of this new scheme.
