摘要 针对二进制相移键控调制的二维扩频系统,分析了其抗单音干扰的性能。通过采用导引符号辅助相干解调进行信道估计的方法,给出了二维扩频系统在单音干扰环境中的误比特率分析结果,并对理论分析进行了仿真。仿真结果表明二者能够吻合及单音干扰对于系统性能的影响。 The current analysis focuses on the performance of BPSK modulation on 2-dimensional spread spectrum system with single-tone jamming. The Bit Error Ratio （BER） of the system is analyzed with the method of pilot symbol assisted modulation. Also the simulation result of the BER is provided and shows that the simulation and the analytical result are almost the same. The result derives the effect of the jamming on the system.
