Joint MIMO and MAI Suppression for the HSDPA

We consider the use of a specific type of Clipped Soft Decision (CSD) – Parallel Interference Cancellation (PIC), optimized for Multiple-Input- Multiple-Output (MIMO) operation. It is shown that the use of the MIMO combined with the proposed PIC scheme can achieve a high performance improvement over the correspondent schemes, and hence, the High Speed Downlink Packet Access (HSDPA) is able to increase the data rate, also with a performance improvement in the Bit Error Rate (BER).
