Abstract
In TxAA HSDPA downlink a basestation is capable of serving several users simultaneously. The users are distinguished by different spreading sequences and their data chip streams are weighted by individual precoding coefficients. In this contribution we derive an MMSE equalizer for TxAA HSDPA downlink that takes the interference of the other users into account. Compared to the straightforward receiver that neglects the interference of other users, a performance gain of up to 4 dB can be achieved.
