Abstract :
The system of cdma2000 1x EV-DO is introduced to provide fast and efficient broadband wireless access. Up to now, there are three versions, mentioned as reversion 0, A and B. A great number of techniques, such as hybrid-ARQ, adaptive modulation and coding, as well as multi-user diversity, support the system to have higher spectral efficiency and better performance. In this paper, technical background and some salient features of EV-DO are summarized. In order to evaluate the DO network performance, the system level simulation is considered based on appropriate assumptions and parameters. Four hot advanced techniques, the distributed token bucket rate control mechanism, reverse link interference cancellation, forward link equalizer and multi-carrier, are deployed and judged in the existing EV-DO system. From simulation analysis and discussions, dual receive antennas, equalizer and interference cancellation may improve the average sector throughput in forward and reverse link respectively. Furthermore, multi-carrier technique could obviously enhance the overall system performance.
