In this Letter a simple noncoherent detection method for chaos-shift-keying (CSK) modulation is proposed, exploiting some distinguishable property of chaotic maps for recovering the digital message. Specifically, the proposed method exploits the difference in the return maps of the signals representing the digital symbols. The determining parameter of the return maps is estimated using a simple regression algorithm. If the parameter strongly characterizes the chaotic map, the detection can achieve very good accuracy. This strong parametric characterization can be achieved by defining the regression model with only one parameter. Using the tent maps as chaos generators, the bit-error-rate under additive white Gaussian noise is studied by computer simulations.<\/jats:p>","DOI":"10.1142\/s0218127403006790","type":"journal-article","created":{"date-parts":[[2003,4,8]],"date-time":"2003-04-08T11:12:24Z","timestamp":1049800344000},"page":"685-690","source":"Crossref","is-referenced-by-count":13,"title":["A RETURN MAP REGRESSION APPROACH FOR NONCOHERENT DETECTION IN CHAOTIC DIGITAL COMMUNICATIONS"],"prefix":"10.1142","volume":"13","author":[{"given":"CHI K.","family":"TSE","sequence":"first","affiliation":[{"name":"Department of Electronic and Information Engineering, The Hong Kong Polytechnic University, Hong Kong, China"}]},{"given":"FRANCIS C.
