Chaos-based anytime reliable coded communications over fading channels with and without information aging

We show that two chaos-coded modulation schemes, that are proved to be anytime reliable on the AWGN channel, can also work in time-varying fading channels. In particular, we devise a transmission scheme that takes advantage of transmitter channel-state information and show by simulation that, whenever such CSI undergoes information aging, the schemes can lose their anytime reliability property.
