Receiver Structures for Fading Channels In this chapter,realizablereceiverstructures synchronized for detectionon flat and selective fading channelsare derived and discussed.Keeping the interaction betweensynchronizationand detectionpathsat a minimum results in receiversof low complexity. As motivated below, we shall concentrate the so-calledinner on receiver, its components,and the necessary synchronizationtasks. 13.1 Outer and Inner Receiver for Fading Channels In compliancewith Shannon’sthird lessonlearnedfrom information theory: “make the channel look like a Gaussianchannel” [ 11, we have distinguished between an outer and inner receiver [2] in the introduction of this book. The sole - yet by no meanstrivial - task of the inner...
