The real issues of communicating over radio channels with continuous time chaotic signals are addressed. Synchronized and nonsynchronized methods are assessed. The modeling of radio channels (including multipath and Doppler) is reviewed, and then the effect on chaotic signals is investigated. The bandwidth efficiency of chaotic communication systems is discussed, and compared to conventional methods. The practical issues of symbol synchronization and equalization are discussed. It is pointed out that discussing these systems as spread spectrum is often unhelpful, because a noise free reference signal is not available at the receiver to exploit the excess bandwidth
