Abstract :
Employing complex scrambling code (CSC) would introduce quasi-orthogonal address code interference (QOACI) in QPSK I-Q sub-channel, resulting in the decrease of the system capacity, presenting two ameliorated scrambling code schemes, then according to the simulation result, because of the complicated constellations, the system capacity would decline correspondingly.
