Both are designed to jointly suppress both intersymbol and multiple\u2010access interference inherent in such systems, and exploit all available time and frequency diversity. The first is a family of linear receivers for time\u2010varying multiuser channels that generalize familiar linear equalizers designed for traditional single\u2010user linear time\u2010invariant channels. Minimum mean\u2010square error, zero\u2010forcing, and matched\u2010filter versions of such multiuser detectors are all developed within a common state\u2010space framework, and have convenient recursive implementations. Performance issues as well as natural decision\u2010feedback variants of the detector structure are both discussed. The second is a family of nonlinear receivers that are specifically designed for use with spread\u2010signature CDMA systems on time\u2010varying multipath channels. These multiuser detectors employ a batch\u2010iterative (multipass or \u201cturbo\u201d stayl) decoding algorithm based on a successive\u2010cancellation strategy. Several aspects of the performance of this algorithm are developed, including its monotonic convergence property. Collectively, these two classes of algorithmic structures for joint equalization, interference suppression, demodulation, and detection are representative of several emerging and interrelated approaches to receiver design for next\u2010generation CDMA systems.<\/jats:p>","DOI":"10.1002\/ett.4460090503","type":"journal-article","created":{"date-parts":[[2008,9,12]],"date-time":"2008-09-12T16:33:10Z","timestamp":1221237190000},"page":"403-418","source":"Crossref","is-referenced-by-count":19,"title":["Joint intersymbol and multiple\u2010access interference suppression algorithms for CDMA systems"],"prefix":"10.1002","volume":"9","author":[{"given":"Soosan","family":"Beheshti","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gregory W.","family":"Wornell","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Steven H.","family":"Isabelle","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\/18.42183"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1109\/26.52661"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1109\/26.339839"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.1109\/18.391241"},{"key":"e_1_2_1_6_2","volume-title":"Wireless Communications: Signal Processing Perspectives","author":"Honig M.
