Abstract:

Multiuser detection in TDMA and CDMA systems is considered based on multi-variable DFEs. In the TDMA case the performance is evaluated on both simulated and real measurement data. It is shown that the proposed DFEs can improve the performance considerably.

The proposed DFEs are also used in a downlink W-CDMA case. The achievable performance in such a case is not sensitive to the structure of the multiuser detector. Also, contrary to what is known from uplink scenarios, the conventional detector performs rather well, particularly when the signal to noise ratio is low.
