摘　　要：研究变换域通信系统(TDCS)独特的频谱利用方法,对其净化干扰的能力进行分析.在阐述变换域通信技术特点和基本原理的基础上,设计其实现框图,并利用MATLAB对变换域通信系统的干扰抑制能力进行仿真.仿真结果表明,变换域通信系统能自适应躲避干扰,具有较强的干扰抑制能力,与OFDM,MC-CDMA相比具有更好的误码性能.The particular spectrum-using means and interference suppression capability of transform-domain communication system （TDCS） were studied and analyzed. Based on the discussion of its basic principle and main technical characteristics, a flowchart of the TDCS was designed, and its interference suppression capability was simulated with MATIAB. The results indicate that the TDCS can evade interference adaptively and has strong capability in interference suppression. Its BER performance is better than that ofOFDM and MC-CDMA.
