Abstract
We propose a secure communication system using interleaved ergodic chaotic parameter modulation. The method is implemented on software defined radios. We show that even if the interceptor knows the interleaving pattern and has a close guess of the spreading gain, the bit error rate (BER) could be still as high as 0.466 because the bits are misaligned. We further combine the ECPM with orthogonal frequency-division multiplexing (OFDM). The OFDM mechanism provides another layer of protection for the information. Our experiments show that the interceptor may have a BER as high as 0.463 even if he correctly guessed 184 out of the 192 subcarriers occupation.
