Comparative Analysis of Power Control Algorithms in CDMA System using Optimization Techniques

Dr. Manish Rai; Chandra Prakash

However, the power control in CDMA systems, allows multiple users to share resources of the system equally between themselves, leading to increased capacity. With appropriate power control, capacity of CDMA system is high in comparison to frequency division multiple access (FDMA) and time division multiple access (TDMA). For power control in CDMA system optimization algorithms i.e. genetic algorithm & particle swarm algorithm can be used which determines a suitable power vector [1], [2]. These power vector or power levels are determined at the base station and told to mobile units to adjust their transmitting power in accordance to these levels. The performances of the algorithms are investigated through both analysis and computer simulations, and compared with well-known algorithms from the literature.
