Abstract :
The behavior of chaos coded modulations (CCMpsilas) in the field of digital communications has been mainly evaluated in additive white Gaussian noise (AWGN) and multipath fading channels. We study here some examples of CCMpsilas over channels with time-invariant intersymbol interference (ISI). We provide bounds for low ISI levels and we show that these chaos-based coded systems can offer reasonable degree of robustness compared with similar coded modulation systems. We provide the analytical condition a CCM has to comply to stand a limited quantity of ISI. Our results are straightforwardly applicable to chaos-based systems of the same kind and provide a hint of the potentialities of CCM systems over dispersive channels.
