Abstract

For the digital-AMPS (D-AMPS or IS-136) standard, performance gains for diversity and interference cancellation are quantified for a prototype system that implements a combination of array processing and adaptive equalization using MLSE techniques. For the site location, field tests show a 3.5 dB C/N improvement at 1% bit error-rate for a four-branch space and polarization diversity receiver relative to a receiver with two space diversity antennas. A 5 dB C/I improvement is observed for an interference cancellation receiver with two antennas and one interferer present, and 9 dB gain in C/I is measured for a combined space-polarization diversity antenna configuration. Furthermore, measurement results confirm that interference cancellation performance is not dependent upon the angular separation between the desired and interfering mobiles
