Abstract: The objective of this project is to study a method how to select the best adaptive code modulation (ACM) out of multiple candidates available in a coherent frequency-hopping (FH) wireless communication system under time-varying jamming and time-varying channel fading. An M-ary phase shift keying (MPSK) coherent modulation will be studied because it is a bandwidth efficient coherent modulation and being used in the commercial digital video broadcasting—second generation satellite (DVB-S2) communications. And to make the communication system robust, a partial-band tone jamming (PBTJ) will be considered because it can be an effective jamming strategy against the MPSK. A typical satellite channel is under a Rician fading environment, and hence will be considered. The results obtained through the project research are expected to be useful in the design of the commercial coherent FH satellite communications systems.
