In this paper, the authors address Multiple Input and Multiple Output (MIMO) techniques within 3G WCDMA. It begins with an overview of MIMO theory and presents WCDMA physical layer and recent High Speed Downlink Packet Access (HSDPA) enhancement to the WCDMA standard. Furthermore, MIMO channel models used in WCDMA performance evaluation were also discussed. The distance between base stations is of little influence on capacity loss of TD-SCDMA uplinks, while the capacity loss of WCDMA uplinks will increase as the distance between base stations increases.
