Implementation and analysis of dual antenna diversity reception using measured impulse responses in cdma2000 system

The paper discusses dual antenna reception in cdma2000 mobile terminal receivers. Realistic performance gains of dual antenna receivers can be provided by taking into account the effects of correlation and branch power difference between the antennas. This is realized by modeling the channel with raw measured impulse responses. The simulation results show that using dual antennas in a terminal handset can provide significant performance gains. The shown gains are optimistic, however, in the sense that the used channel data mostly consist of channel situations where only one significant tap is present that evidently favors diversity reception. The presented finger allocation methods for dual antennas perform well in cellular environments where a sufficient number of fingers is available. However, with a low number of fingers, performance differences between the methods were found.
