中文摘要：
提出用基带预滤波技术改善完全响应连续相位频移键控（CPFSK）信号的综合性能，这一技术在等效Eb／No增益与信号带宽方面进行了合理折衷。数值分析表明，有两类窗族预滤波方案，当参数β值选择较合适时，能实现包括RC、SRC、HCS在内的几乎所有基带预滤波。这两类窗族分别是Kaiser窗族和幂次窗族基带预滤波。经过计算机仿真，得出4CPFSK和8CPFSK条件下，基带预滤波技术的等效Eb/No增益与带宽的数值关系。这一关系对基带预滤波技术在工程上的应用具有指导意义。
英文摘要：
Baseband pulse shaping is proposed to improve the overall performance of full response CPFSK signals because this technique makes reasonable tradeoff between Eb/No gain and bandwidth. Numerical results show that by choosing appropriate parameterβ, previously derived baseband pulse shaping schemes like RC, SRC and HCS can be included into two window pulse shaping families. One is Kaiser window pulse shaping, the other is called ＂power window＂ pulse shaping. Computer simulations, which aim to acquire the numerical relations between Eb/No gain and bandwidth, are made for those two window families in the case of 4CPFSK and 8CPFSK. The results provide guidance for practical uses.
