针对当今无线频谱稀缺的窘状，提出了一种非正交频分复用（Non-Orthogonal Frequency Division Multiplexing， NOFDM）的传输方案。与当今最为流行正交频分复用（Orthogonal Frequency Division Multiplexing，OFDM）相比，该方案在一定程度上提高了频谱效率。在接收端，进行最大似然检测。通过理论推导以及仿真证明了该方案的可行性。

For the embarrassing situation about the spectrum scarcity, this paper proposes a non-orthogonal frequency division multiplexing (NOFDM) transmission scheme. In comparison with OFDM system, which is the most popular technology nowadays, this scheme can improve the spectrum efficiency. At receiver, the maximum likelihood (ML) detection is introduced. By mathematical derivation and simulation, the feasibility of the scheme is verified.
