中文摘要：

非直角的时间频率部门 multiplexing (NTFDM ) 传播计划被建议了进一步改进带宽效率并且克服常规直角的频率部门 multiplexing (OFDM ) 的缺点方法。基于如此的途径，快信号察觉算法， semidefinite 编程(SDP ) 察觉，被学习了。当系数矩阵趋于是调节的病，修改 SDP 算法与连续干扰取消结合了(原文如此) 被开发了。改进算法是在性能和察觉复杂性之间的好折衷。模拟结果比切飞机帮助了 SDP 方法证明建议算法能完成更好的性能。

英文摘要：

Non-orthogonal time-frequency division multiplexing （NTFDM） transmission scheme has been proposed to further improve the bandwidth efficiency and overcome the drawbacks of the conventional orthogonal frequency division multiplexing （OFDM） method. Based on such approach, the fast signal detection algorithm, semidefinite programming （SDP） detection, has been studied. As the coefficient matrix tends to be ill conditioned, the modified SDP algorithm combined with successive interference cancellation （SIC） has been developed. The improved algorithm is a good tradeoff between performance and detection complexity. Simulation results show that the proposed algorithm can achieve better performance than cutting plane aided SDP method.
