Abstract A chaotic sequence for chaos shift keying (CSK) that provides auto- and cross-correlation properties (that are similar to those of random white noise) is used for spread spectrum systems. Due to its bifurcation behavior (depending on the initial condition), the number of chaotic sequences that can be generated by a single formula is not restricted and will not repeat itself. These characteristics provide an increase in system capacity and security performance. The paper presents a study of two different commonly used chaotic logistic maps and a modified chaotic logistic map for CSK spread spectrum system. The newly modified logistic map provides similar bits error rate (BER) performance to the best logistic map. Yet, it also provides an additional chaotic parameter for the control of its dynamic property, hence increasing the system security and capacity.
