Abstract :
In the paper, BER (bit error rate) performance of MA-CSK (multiple access chaos shift keying) is studied to find out what factors govern the performance of MA-CSK system. Further, it is investigated how each factor take impact on BER performance. Through theoretical analysis and computer simulation, it is verified that better BER performance for a certain user is contributed by lower autovariance of square of chaotic sequence and autocorrelation of chaotic sequence, smaller number of users and bigger spreading factor.
