Performance evaluation of reverse link for speech and data traffic in CDMA-based IMT-2000
Bub-Joo Kang · 2003
In this paper, the bit error rate (BER) performance for the speech and data traffic is evaluated by results of the reverse link simulation of CDMA-based IMT-2000. Simulations in the reverse link are achieved 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 BER performance according to the number of fingers, and performance comparison between convolutional code and concatenated code at 10/sup -6/ BER in 5 MHz system.
