Abstract(in English) The performance of the complete orthogonal spreading sequences in the synchronous CDMA with radio frequency (RF) modulation is investigated. We use the Chebyshev chaotic sequences recovered by Independent Component Analysis (ICA) proposed before and the Walsh-Hadamard sequences as the spreading sequences. It is found analytically and numerically that Bit Error Rate in the synchronous CDMA with RF modulation using these sequences is larger than that in baseband when the additive white Gaussian noise has finite value. The analytical form of Bit Error Rate (BER) in the chip-synchronous CDMA with RF modulation using any kind of spreading sequences is obtained. Using this, we found that there is a critical value of noise power where the magnitude relation between BER in baseband and the one with RF modulation changes.
