Adaptive neuro-fuzzy power control and rate adaptation for multirate CDMA radio systems

Emerging multimedia services in cellular radio systems introduces a communication scenario with variations in transmission rate and quality of service (QoS) requirement. To tackle this problem, a new application of neuro-fuzzy control to the power control strategy in multirate direct-sequence code-division multiple-access (DS/CDMA) cellular radio systems is introduced in this paper. The simulation results indicate that the neuro-fuzzy power control (NFPC) provides higher average transmission rate, lower probability of unsuccessful transmission, and less outage probability than the previous mechanisms.
