Unformatted text preview: 1 EE522 Communications Theory Spring 2010 Instructor: Hwang Soo Lee Lecture #14 – MSK & Performance of Measures: BER, Packet Error Rate Conclusion of Modulation 2 Minimum Shift Keying (MSK)- A Form of FSK ¡ For FSK ¡ For orthogonality 3 Orthogonality of FSK Signal Set (Continued) ¡ For orthogonality 4 Orthogonality of FSK Signal Set (Continued) ¡ The first zero of sinc( π x) is for x=1. Thus we set ¡ This gives the minimum frequency separation for orthogonality ¡ There is perhaps a problem. 5 Orthogonality of FSK Signal Set (Continued) ¡ For both signals to go through an integer number of cycles in a bit period we must have ¡ For m=1 we have standard FSK. 6 CPM - Definitions ¡ We define the signal set ¡ In general we may write 7 CPM - Definitions (Continued) ¡ The phase deviation contains all of the past information about the signal and, therefore, all of the information about the information sequence....
