The computational intensity required, however, increases exponentially with the spreading factor. In this Letter, we propose an approximate-optimal detection technique, whose computational effort increases only linearly with the spreading factor. In particular, we use the chaotic sequences generated by a skew tent map as an example to illustrate the approximate-optimal detection method. The bit error performance of the proposed detector is evaluated by computer simulations and the results are compared with those obtained using the optimal detector.<\/jats:p>","DOI":"10.1142\/s0218127403007266","type":"journal-article","created":{"date-parts":[[2003,6,25]],"date-time":"2003-06-25T00:53:09Z","timestamp":1056502389000},"page":"1329-1335","source":"Crossref","is-referenced-by-count":9,"title":["APPROXIMATE-OPTIMAL DETECTOR FOR CHAOS COMMUNICATION SYSTEMS"],"prefix":"10.1142","volume":"13","author":[{"given":"FRANCIS C.
