CDMA receiver performance for multiple-input multiple-output antenna systems
Mohamed I. Ahmed, J. Pautler, Kamyar Rohani · 2002
We consider the performance of a forward link (base-to-mobile) shared channel with and without a multiple-input multiple-output (MIMO) antenna system. A CDMA shared channel is analyzed and simulated for which users are served in a time division multiplexed (TDM) manner. The slot structure and chip rate are based on the wideband CDMA standard. Link-level simulations are presented to compare the performances of two different receivers: linear minimum mean-square-error (MMSE), and nonlinear (turbo/iterative) MMSE. In addition, MIMO performance is compared with and without antenna array weight feedback.
