Synchronization of Discrete-Time Chaotic Systems in Bandlimited Channels

Figure 8

Simulations of the proposed communication system for an LP FIR channel with cutoff frequency at 𝜔_𝑐=0.8𝜋 and LP FIR feedback filter 𝐻_𝑆(𝜔) with cutoff frequency at 𝜔_𝑆=0.7𝜋: (a) message 𝑚(𝑛); (b) transmitted signal 𝑠(𝑛); (c) received signal 𝑟(𝑛); (d) recovered message 𝑚^′(𝑛).
