Abstract

This paper presents the algorithm and the result of a novel demodulation technique for a chaos-based CDMA system. Standard CIC filters are applied for interpolating the transmitted signal, in order to retrieve more sample points without increasing the systempsilas bandwidth. Then the original binary message for each user is retrieved by means of a support vector machine demodulator. Simulation results show that this new approach significantly outperforms the conventional method of using matched filters by 7 to 10 dB.
