Description
Summary:An obstacle of orthogonal frequency division multiplexing (OFDM) multiple-input multiple-output system is using cyclic prefix (CP) which leads to loss of bandwidth. It is a challenge of the high utilization rate for modern communication systems. In order to eliminate the impact of CP of OFDM, non-orthogonal multiple-modulation (NOMM) is introduced for MIMO system. Relevant error probability and bandwidth efficiency are meliorated because of the breakthrough constraints of orthogonal. A novel constellation design is proposed for NOMM, which enhances the performance resisting interference and obtain the capacity gain. NOMM offers a more effective method in practice and indicates a broad development for modulation techniques in theory as well.
