Abstract :
In Frequency-Modulated Differential Chaos Shift Keying (FM DCSK) modulation scheme, the digital information to be transmitted is mapped to an inherently wide-band chaotic signal rather than to a sinusoidal carrier. In this sense, the FM-DCSK system offers a new solution to spread spectrum communications. The FM-DCSK can be used in every application where multipath propagation rather than thermal noise limits the overall system performance. Because there is no need for synchronization at the FM-DCSK demodulator, this modulation scheme is very robust against channel disturbances and distortion. This paper evaluates the multipath performance of the FM-DCSK system in WLAN application by computer simulation
