CDMA2000 1xEV standard, also known as IS-856, is a next generation solution to high speed wireless internet access. This paper explores the possibility of improving the reverse link performance (in terms of coverage and data throughput) of IS-856 using adaptive antenna array receivers. Specifically, it considers the effect of array size, configuration and discuss how we can tradeoff the antenna gains via adjustment in MAC layer protocols. Paper looks at spatially separated antenna arrays as well as pairs of cross-polarized (X-pol) antennas. The key difference between our study and many existing smart-antenna results is that this paper considers the dynamics associated with power-control and upper-layer algorithms in addition to the physical-layer interactions.
