摘要：

In this paper, a noncoherent chaotic shift keying with suboptimal recovery scheme is designed. The scheme uses a nonlinear chaotic map and its inverse for generating the chaotic sequence. The selection between two maps depends on the value of the input data bit. The suboptimal receiver decodes the received sequence for bit "1" or "0" by calculating the shortest distance between the sequence and the trajectory of the chaotic maps. The standard logistic map is first used for generating the chaotic sequence of length N samples per data bit. Then a modified logistic map is proposed to increase the reliability of signal in noisy channels. The results show that the suboptimal detection based on modified logistic map over perform the one based on classical logistic map. The results also show that the detection performance is improved as N increased.
