Abstract :
This paper proposed a novel reconstruct the training sequence algorithm to cancel the MAI in the Orthogonal Frequency Division Multi-access (OFDM) system. Compared with previous algorithms, the proposed algorithm improved the SIR and CFO estimation performance by utilize different SIR and CFO efforts. The numeric results show that the performance of CFO estimation for Multi user or multi-access in the frequency selective fading channel based on OFDM uplink may decrease the inter-carrier interference ICI as well as single user case.
