The Nyquist rate is a limit of transmission for traditional modulation methods from orthogonality restriction. Nonorthogonal modulation techniques (NMT) is proposed, which removes the orthogonality restriction, and as a result, higher bandwidth efficiency than the traditional methods can be achieved. First, the symbol error rate of NMT is introduced by(More)
OFDM is a practical modulation technique with highest frequency efficiency at present and it has been adopted by many international communication standards. In this paper a novel time-shift non-orthogonal multi-carrier modulation (TS-NMCM) technology which has higher bandwidth efficiency and more outstanding technology performances than OFDM is introduced;(More)
