Throughput Analysis of Per-Antenna Rate Control With Linear Chip-Level Equalization
In this paper the achievable performance gains of Per-Antenna Rate Control (PARC) for Code Division Multiple Access (CDMA) transmission with different linear chip-level equalization algorithms are investigated. High Speed Downlink Packet Access (HSDPA) as a solution of a full packet-based transmission standard utilizes extensive multi-code 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.
