Forward and reverse link capacity for 1xEV-DO: third generation wireless high-speed data systems

Abstract

This paper presents the performance results of a 1xEV-DO system. With different fading channels, data rate control lengths and overhead channel power levels, the system performance will vary. While optimizing the forward-link throughput becomes critical for asymmetric traffic demand, it is important to ensure that the reverse-link throughput is sufficient to support the data traffic ratio of 4:1 to 6:1 (forward/reverse). In this paper, the forward-link throughput is simulated. The final throughput is based on field measured channels for different morphologies. On the reverse link capacity, the throughput is analyzed based on an analytical formula that considers pilot, DRC and data channels.
