Abstract
In this paper, we study the improvement in the reverse link budget due to base-station smart antennas in CDMA cellular networks. Considering a typical multipath propagation environment, we quantify the excess energy per bit to interference plus noise ratio /spl gamma//sub b/ due to smart antenna processing at the base station as a function of the number of sensors, their separation, and scattering angle, With this excess /spl gamma//sub b/, we evaluate different trade-offs between different performance measures such as capacity, area coverage, and mobile transmitted power. Both theoretical and simulation results are presented.Keywords
