Abstract :
Direct sequence code division multiple access (DS-CDMA) techniques have received a great deal of attention for current and future communication systems. One of the major considerations in implementing a DS-CDMA system is the necessity for accurate power control to ensure adequate quality-of-service and capacity. This paper investigates the power control errors that occur in a real microcellular environment for a variety of architectures. Furthermore, the mitigation of the effect of power control errors with varying spreading bandwidth is quantified
