Abstract :
Due to the availability of potentially large sets of sequences with good correlation characteristics, the interest in the implementation of complex spreading sequences (CSS) in code division multiple access (CDMA) systems, has increased dramatically. In this paper, the simulated bit error rate (BER) performance of a synchronous balanced quadrature phase shift keying (QPSK) CDMA system, employing different classes of CSS, is presented for Gaussian and multipath fading channel conditions
