HSDPA and MIMO

HSDPA is a packet-based data service in W-CDMA downlink with data transmission up to approximately 10 Mbps over a 5MHz bandwidth
MIMO technology is used, in which multiple antennas are implemented at both base station and mobile terminals to attain a speed of 20Mbps .
At the transmitter, the information bits are divided into several bit streams and transmitted through different antennas.
The transmitted information are recovered from the received signals at multiple receive antennas by using an advanced receiver.
Due to the high data rate transmission, the trade off between complexity and system performance becomes an important issue, especially for the UE designs.
