Analytical BERs of Coherent CSK and Noncoherent DCSK Systems with Multiple Users
نویسندگان
چکیده
Several chaos-based digital communication schemes have been proposed in recent years. Unlike conventional modulation systems where analytical bit error rates (BERs) can be found given a certain bit-energy-to-noise-psd ( ) ratio, BERs of chaos-based digital communication systems are mainly found from simulations or experiments. In this paper, we present an analytical method to derive the BER of coherent CSK and noncoherent DCSK modulation schemes with multiple users. A 3-user system has been simulated and the results are compared with the proposed analytical approach.

Analysis of Performance of Noncoherent DCSK Communication Systems Over a Multipath Rayleigh Fading Channel with Delay Spread
Abstract— The performance of the noncoherent differential chaos-shift keying (DCSK) communication system over a multipath fading channel with delay spread is evaluated. Analytical expressions of the bit error rates are derived under the assumption of an independent Rayleigh fading two-ray channel model. Analytical and simulated results are presented and compared. The multipath performance of th...
متن کاملAnti-Jamming Performance of Chaotic Digital Communication Systems
Among the various modulation schemes proposed for chaos-based digital communications, chaos-shift keying (CSK) and differential chaos-shift keying (DCSK) have been most thoroughly analyzed and considered for practical implementation. One important aspect of performance of any communication system is the ability to resist jamming. This area of study, however, is not available in the literature. ...
