In the proposed system, the channel filter is placed before the acquisition system to overcome the multipath delay and co\u2010channel interference effects. Monte Carlo simulation is used to evaluate and compare the performance of the system in terms of multi\u2010user interference and multipath delay both with and without the proposed channel filter. Results show that the proposed technique can significantly improve the overall system performance. Details of the system configuration, the design concept of the channel filter and the simulation techniques used are discussed.<\/jats:p>","DOI":"10.1002\/ett.4460080305","type":"journal-article","created":{"date-parts":[[2008,9,12]],"date-time":"2008-09-12T13:39:29Z","timestamp":1221226769000},"page":"243-250","source":"Crossref","is-referenced-by-count":0,"title":["Improving the performance of CDMA systems in a multipath delay and fading environment"],"prefix":"10.1002","volume":"8","author":[{"given":"Lan","family":"Hu","sequence":"first","affiliation":[]},{"given":"Cyril J.","family":"Burkley","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2008,9,12]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1109\/JRPROC.1958.286870"},{"key":"e_1_2_1_3_2","unstructured":"U.Fawer:Rake\u2010receivers for direct\u2010sequence spread\u2010spectrum (DSSS) system.
