Abstract

We describe computer simulation and laboratory performance results of a real-time two-element adaptive antenna array testbed for the uplink of a 1.9-GHz IS-136 PCS base station. Our simulations and real-time experimental results with a channel emulator show less than a 1-dB implementation loss as compared to theoretical results for the noise-only case. With interference, at low fading rates the implementation loss to is only a few decibels. However, the performance degrades with increasing fading rate, such that the adaptive array performance is similar to maximal ratio combining at 60-m/h fading rates (179 Hz at 1.9 GHz).
