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 communication capacity, presenting two ameliorated scrambling code schemes, then according to the simulation result, because of the more complicated constellations, the capacity would decline correspondingly.
