Abstract: In this paper the achievable performance gains of Per- Antenna Rate Control (PARC) for Code Division Multiple Access (CDMA) transmission with different linear chiplevel equalization algorithms are investigated. High Speed Downlink Packet Access (HSDPA) as a solution of a full packet-based transmission standard utilizes extensive multicode operation especially in low-mobility scenarios. Due to possible large delay spreads resulting from multipath propagation, the orthogonality of the spreading codes is destroyed, which leads to severe performance degradations. To cope with such properties of mobile radio channels, chip-level equalization was suggested to be an advanced receiver technique in future user equipments. Simulations for PARC with chip-level equalization, which include adaptive modulation and coding as well as feedback errors and delays, show that throughput can be signicantly increased at high signal-to-interference-and-noise ratios compared to common Rake reception if multiple codes are assigned to a single user.
