Dagmar Bosanska, Christian Mehlfuhrer, Markus Rupp
2008 2008 International ITG Workshop on Smart Antennas  
In this paper we compare interference cancelation to MMSE equalization in the context of D-TxAA (Dual Stream Transmit Antenna Array) HSDPA. The interference cancelation is carried out in three steps.  ...  After canceling the deterministic channels (pilot and synchronization channel), one user data stream is reconstructed by an MMSE equalizer.  ...  The equalizer for the second stream is calculated analogously to (14) by using the reduced precoding matrix W = 0 w (2) 1 0 w (2) 2 . (16) SIGNAL CANCELATION ORDERING When interference cancelation is  ...
