Coded Modulation and Bandwidth-Efficient Transmission: Proceedings of the 5th International Workshop, Tirrenia, Italy, 8-12 September, 1991

Almost two decades ago, by using random coding bound arguments, it was proved that considerable progress in the power efficiency of digital communication could be obtained by treating coding and modulation as a single entity. These ideas were carried further in the manifestation of Trellis Coded Modulation (TCM) techniques. Sine then, the idea of TCM has expanded greatly beyond the type of schemes originally presented, and has given way to a considerable amount of research activity, both theoretical and applied, and to the implementation of several TCM techniques in new generations of modems. Block-Coded Modulation (BCM) was discovered at about the same time as TCM, and is currently attracting considerable interest as a possible alternative to TCM for some applications. A thorough overview on both kinds of coded modulation is discussed in this volume. It assesses the status and the prospects of coded modulation and of bandwidth-efficient transmission, shedding light on the future avenue of theory and applications in these exciting areas.
