Abstract

Power distribution for multicode code division multiple access (MC-CDMA) systems supporting heterogeneous services is investigated. Power distribution laws under perfect and imperfect power control conditions are derived for the MC-CDMA systems to satisfy the required quality-of-service (QoS) while supporting more simultaneously transmitting users. Numerical results calculated based on the analyses are shown to demonstrate the impact of imperfect power control on the required receive powers
