摘　　要：本文详细讨论了二进制多h连续相位移频键控(CPFSK)信号的最小平方欧几里德距离(MSED),提出了决定MSED的信号隔离度的概念。为了获得最大的MSED,则应使信号隔离度N_s尽可能大,所以本文在理论上系统地推导了信号隔离度取最大值时所应满足的充分和必要条件。最后,本文还讨论并给出了2-h CPFSK信号的隔离度及其MSED的精确求解公式。The minimum squared Euclidean distance (MSED) of 2-ary multi-k continuous-phase frequency-shift keying (CPFSK) signal is presented. The signal segregation degree (SSD) has been put forward to determine MSED of CPFSK. In order to maximizing MSED, SSD should be as large as possible. The full and essential conditions of maximizing SSD N, are derived. Finally, SSD N, and the exact formulae for the MSED of 2-ary 2-h CPFSK are also presented.
