Simplified Receivers, four different methods for constructing simplified suboptimum coherent receivers for CPM. We will see that their level of complexity, performance degradation, and degree of applicability are interconnected.

,Energy—Bandwidth Comparisons and Shannon Theory for Phase Modulation,me if large energy is available, and similarly high energy is not needed for a low error probability if a large bandwidth can be tapped. What is much more difficult is reducing one of these without reducing consumption of the other.

Transmitters, multi-. schemes and coded phase modulation are not considered, but it is straightforward to generalize the transmitters that we discuss. We will first give some general structures and then discuss the practical implementation aspects of each with a few special cases in mind. More details on this su

Receivers,hat the carrier phase and the symbol timing are precisely known by the receiver. Methods for extraction of these parameters from the received noisy signal are discussed in Chapter 9. Noncoherent reception will also be considered. In this case we assume that the receiver only knows the symbol timing

Synchronization, available. This is referred to as synchronization. To avoid wasting power, these signals should not be transmitted separately, but should instead be regenerated at the detector in an optimum manner. Actually, both the transmitted data sequence and the reference signals should be estimated jointly a
