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. This data stream is transmitted over a replicated "virtual" channel and its output subtracted from the received signal. From the remaining received signal we reconstruct the second data stream by a second equalizer. Our performance evaluation is based on the physical layer coded data throughput. The interference cancelation receiver shows large performance gain (approx. 2.0 dB) over the state-of-the-art MMSE equalizer while the complexity is only increased slightly.
