The codes are \u201cmultiple\u201d TCM (MTCM) codes as proposed by Divsalar and Simon \u2013 i.e., codes in which multiple symbols are associated with each transition through the trellis; by applying appropriate puncturing tables to low\u2010rate MTCM codes we obtain families of MTCM codes, all of which can be decoded with (essentially) the same decoder. By means of computer search, several such families are obtained so that each family member is at least as good as any comparable code in the literature. (\u201cGood\u201d here is defined in terms of minimum time diversity and minimum squared product distance, the most important parameters for performance over Rayleigh fading channels). A protocol to implement these rate\u2010compatible trellis codes in a type\u2010II hybrid ARQ format is described. The proposed protocol selectively punctures symbols from the low\u2010rate code based on the observed fading values observed on each branch. Upper bounds on the resulting bit error rate are developed and the results are used to select the best adaptive code from several possibilities. Simulation results comparing the proposed scheme with fixed\u2010rate codes of the same throughput show substantial coding gain. Finally a protocol modification limiting the variability of the code rate over a frame is described; this modification eliminates the need for excessive buffering, with a very small effect on performance.<\/jats:p>","DOI":"10.1002\/ett.4460090603","type":"journal-article","created":{"date-parts":[[2008,9,12]],"date-time":"2008-09-12T16:21:34Z","timestamp":1221236494000},"page":"483-495","source":"Crossref","is-referenced-by-count":3,"title":["A hybrid\u2010ARQ system using rate\u2010compatible trellis codes designed for rayleigh fading"],"prefix":"10.1002","volume":"9","author":[{"given":"Mustafa","family":"Er\u00f6z","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomas E.","family":"Fuja","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2008,9,12]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1109\/49.44581"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1109\/26.7513"},{"volume-title":"Introduction to trellis\u2010coded modulation with applications","year":"1991","author":"Biglieri E.","key":"e_1_2_1_4_2"},{"key":"e_1_2_1_5_2","doi-asserted-by":"crossref","unstructured":"P.Ho J.Cavers J.Varaldi:The effects of constellation density on trellis\u2010coded modulation on fading channels. \u201cIEEE Trans. on Veh.
