摘　　要：本文对比介绍了单载波调制解调系统BPSK与2DPSK,QPSK与OQPSK的性能,并在System View平台上分别构建了各技术的调制解调模型。通过使用分析窗口和接收计算器,对比观察了各系统抗噪声性能和频谱。验证了在相同信噪比条件下,BPSK误码率小于2DPSK和QPSK,QPSK误码率与OQPSK相同,但BPSK频谱利用率低于QPSK的结论。最后给出了建议。This paper discusses and introduces the performance of BPSK and 2DPSK as well as QPSK and OQPSK. To link each modulation and demodulation models by System View in order to compare and view anti-noise capability and spectrum of each systems with analysis window. This experiment demonstrates the theory that BER of BPSK is lower than 2DPSK and QPSK. In addition, BER of QPSK equals to OQPSK. But spectrum efficiency of BPSK is lower than QPSK. Finally, this paper gives some suggestions.
