Capacity calculation of reverse link in CDMA-based IMT-2000
Bub-Joo Kang, Sunyoung Kim · 2003
In this paper, the capacity for the speech and data traffic is calculated by results of the reverse link simulation of CDMA-based IMT-2000. Simulations in the reverse link are made for indoor, pedestrian, and vehicular environments, which are provided by ITU-R. Also, in these simulations, the fast power control of 1.6 kHz rate is applied. The amplitude and phase of the fading signal are estimated by using the 5-tap FIR filter, and the soft-decision Viterbi and Reed-Solomon (RS) decoding are applied. Simulation results provide the optimum ratio of pilot power to traffic power. The Erlang capacity for speech traffic, and user capacity for data traffic in all channel environments and in multiband systems are provided.
