It is designed for classroom use and for anyone wanting to learn the ideas behind this modern kind of coding. Coded modulation is signal encoding that takes into account the nature of the channel over which it is used. Traditional error correcting codes work with bits and add redundant bits in order to correct transmission errors. In coded modulation, continuous time signals and their phases and amplitudes play the major role. The coding can be seen as a patterning of these quantities. The object is still to correct errors, but more fundamentally, it is to conserve signal energy and bandwidth at a given error performance. The book divides coded modulation into three major parts. Trellis coded modulation (TCM) schemes encode the points of QAM constellations; lattice coding and set-partition techniques play major roles here. Continuous-phase modulation (CPM) codes encode the signal phase, and create constant envelope RF signals. The partial-response signaling (PRS) field includes intersymbol interference problems, signals generated by real convolution, and signals created by low | | 出版日期 | Book 2002 | | 關(guān)鍵詞 | Modulation; Partition; Phase; Shannon; Signal; Symbol; coding; communication; filtering; filters; information; | | 版次 | 1 | | doi | https://doi.org/10.1007/b100498 | | isbn_softcover | 978-1-4757-8737-5 | | isbn_ebook | 978-0-306-47792-8Series ISSN 1389-6938 Series E-ISSN 1866-6361 | | issn_series | 1389-6938 | | copyright | Springer Science+Business Media New York 2002 |
