Abstract :
In this paper we analyze the capacity of a CDMA system supporting integrated voice and data services. The bit energy-to-interference ratios for voice and data services are each modeled using lognormal distributions, and an integrated capacity formula based on a lognormal approximation is proposed. The capacity formula defines an admission scheme to guarantee with a predefined probability the total interference is less than the maximum acceptable interference. Under the assumption of Poisson arrivals for voice and data services, Kaufman´s method is applied to calculate the blocking probabilities for voice and data services. Numerical results are provided to illustrate the proposed procedure.
