摘要：

This paper presents a chaotic oscillator-based binary phase-shift keying (CO-BPSK) modulation scheme, exploiting the chaotic dynamics to achieve carrier phase inversion. A basic analytical expression is derived for the bit error-rate (BER) under additive white Gaussian noise (AWGN) channel conditions, and a baseband complex envelope simulation technique presented for two different chaotic oscillators: the Rossler attractor and the Colpitts oscillator. The proposed modulation scheme enables direct modulation of the oscillator, permits the use of conventional BPSK receiver techniques for synchronization and demodulation, and is shown to achieve competitive BER performance in an AWGN channel.
