Generalized Multi-carrier Chaotic Shift Keying

摘要: Chaotic shift-keying, perhaps better described as chaotic carrier shift keying (CSK), encodes information in the selection of a time-synchronized orthogonal spread spectrum signal and decodes that same by comparing output parallel despreaders. The general performance CSK waveforms lacks coherent single-carrier modulations due to each despreader generating an independent noise statistic potential for inter-correlations between assumed carriers. However, multiple carriers can be employed significantly increase throughput capacity waveform, permitting novel also take advantage other phase or amplitude manipulations, much like OFDM system. This paper generalizes analytical simulation results arbitrary multi-carrier systems, well reports on measured hardware lower-order implementation.
