Generalized RAKE (G-RAKE) and linear minimum mean square error (LMMSE) are two equalization techniques designed for advanced receivers in wideband code division multiple access (WCDMA) / high-speed downlink packet access (HSDPA) systems. In this paper, we first review the theoretical properties and discuss some implementation issues of the G-RAKE technique. The equivalence between G-RAKE and LMMSE...
In this paper a linear multi-user beamforming technique is proposed for frequency-selective channels in multiple-input-multiple-output (MIMO) wideband code division multiple access (WCDMA) system. Assuming perfect Channel State Information (CSI) is available at both transmitter and receiver, transmit beamforming and receive beamforming are coordinated to mitigate multi-user, multiple access (MAI),...
