Performance Analysis of Tomlinson-Harashima Multiuser Precoding in Multipath CDMA Channels
Overview Tomlinson-Harashima multiuser precoding (THP) is a transmitter (Tx)-based multiple access interference (MAI) cancellation technique for Direct Sequence (DS) Code-Division Multiple Access (CDMA) systems. This zero forcing (ZF)-based transmitter precoding method minimizes the mean square error at the receiver. It is suitable for the downlink since the receiver is as simple as the single user matched filter receiver. For frequency-selective fading channels, by combining THP with diversity techniques, two specific designs are developed, PreRAKETHP and Multipath Decorrelating THP (MDTHP), which provide desired performance-complexity trade-off.
