论文从最小频移键控（Minimum Shift Keying ，MSK）信号相位轨迹的角度出发，对 MSK 信号的频谱进行压缩，首先提出了一种经过整形的 MSK（Shaped Minimum Shift Keying ，SMSK）的调制方法，然后与另一种压缩 MSK 信号频谱的经过整形的偏移四进制相位调制（Shaped Offset Quadrature Phase Shift Keying ，SOQPSK ）调制方法进行了对比分析，本文的调制方法有压缩 MSK 频谱的效果，而且比 SOQPSK 更易于实现。

Spectrum suppressing with minimum shift keying signal from its phase trace is focused on this paper .A method called shaped minimum shift keying is proposed at first .The comparison with shaped offset quadrature phase shift keying which spectrum is narrower than MSK is analyzed then .The spectrum frequency of SMSK is higher than MSK and the implementation of SMSK is easier than SOQPSK .
