摘要: 本文詳細(xì)討論了二進(jìn)制多h連續(xù)相位移頻鍵控(CPFSK)信號(hào)的最小平方歐幾里德距離(MSED),提出了決定MSED的信號(hào)隔離度的概念。為了獲得最大的MSED,則應(yīng)使信號(hào)隔離度Ns盡可能大,所以本文在理論上系統(tǒng)地推導(dǎo)了信號(hào)隔離度取最大值時(shí)所應(yīng)滿足的充分和必要條件。最后,本文還討論并給出了2-h CPFSK信號(hào)的隔離度及其MSED的精確求解公式。Abstract: The minimum squared Euclidean distance (MSED) of 2-ary multi-h 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 Ns are derived. Finally, SSD N, and the exact formulae for the MSED of 2-ary 2-h CPFSK are also presented.
