中文摘要：
针对跳扩通信系统中直扩和跳频的二维性，提出了一种时空混沌跳扩通信系统。通过时空混沌，不仅可以增强系统的保密性，又能同时产生实时的直扩序列和跳频图案序列，减小了系统实现的复杂度。此外，文中产生的PN序列和跳频图案序列的周期易于控制，可以任意改变，使系统更加灵活，保密性更高。文中对新构建系统的误码率性能进行了分析，仿真结果表明．该系统具有理想的误码率性能，抗多址干扰能力强，具有非常广阔的应用前景。
英文摘要：
A new hybrid direct Sequence/frequency hopping （DS/FH） communication system is presented based on spatiotemporal chaos. And spatiotemporal chaos strengthen the system security but also generate real time PN codes and FH patterns synchronously by a single mechanism. In this mechanism, it is easier to control the period of PN sequences and FH patterns so as to make the system more flexible and more secure as well as to decrease the realization complexity. The bit error rate performances of multi-user spatiotemporal chaotic hybrid DS/FH communication system are analyzed. Simulation results show that the system has the ideal bit error rate performance and the high capability of multi-access interference, thus having a broad application future.
