Abstract

High speed downlink packet access (HSDPA) is one of the key features in the 3rd generation wireless communication standard for WCDMA. It is ongoing standardization effort to include a high data rate packet mode in the downlink direction, and is characterized by link adaptation using variable constellations (QPSK, 8PSK, 16QAM, 64QAM) and low spreading factor. The proposed MVDR multi-code receiver based on channel estimation is particularly adapted to HSDPA mode, and it gives a reasonable performance even in the case of high modulation order while keeping a lower complexity compare with LMMSE chip equalizer
