Abstract

This paper presents a novel multiple access scheme for future mobile communications using Multi-Symhol Encapsulated Orthogonal Frequency Division Multiplexing (MSEOFDM). MSE-OFDM is a bandwidth efficient OFDM scheme, where a number of OFDM symbols are grouped together as a frame and protected by one single cyclic prefix (CP). This reduces the extent of redundancy caused by the CP and increases the bandwidth efficiency of the system. In the proposed scheme, OFDM symbols for different users are grouped and one cyclic prefix is used for a group of users. Thus, we can get better spectral efficiency as compared to conventional OFDMA. The FFT size is also reduced, which improves the robustness to synchronization errors and reduces the PAPR.
