We considered the relative performance of a number of different BS beam former/DFE configurations for 100-Mb/s QPSK
using a clustered statistical indoor propagation model. We observed a significant SNR improvement for the beamformer case relative to the single omnidirectional antenna case when enough DFE FF taps are provided to fully exploit the in-band diversity in all cases. We determined that tapering was not beneficial in this TDMA interference-free environment. While performance improves as the total number of beams increases, beyond 56 beams, the improvements are small, therefore, cost is likely to heavily influence the choice of the total number of beams.
