Chaotic signals require very wide bandwidth to be transmitted in a practical channel, which is difficult for the practical transducer or antenna to convert such a broadband signal. To address this problem, in this work, Chaotic Shape-forming Filter (CSF) is used to obtain the baseband signal, and the corresponding matched filter is used at the receiver to maximize the signal-to-noise ratio. At the same time, the symbol judgment threshold determined by the chaos properties is used to reduce the Inter-Symbol Interference (ISI) effect. Simulations and virtual channel experiments show that the radio-wave communication system using chaos is inferior to the conventional radio-wave communication system using Square Root Raised Cosine (SRRC) shape-forming filter in a single path channel. This is because SRRC eliminates ISI in single path, but CSF does not. However, the chaos-based communication with anti-multipath decoding algorithm shows significantly better Bit Error Rate (BER) performance than the traditional communication system using SRRC and a minimum mean square error (MMSE) channel equalization in a multipath channel. This work shows the potential application prospect of chaos-based communication in future 5G or 6G engineering communication systems.
