Chip-based Joint Processing Antenna Diversity and Equalize for DS-CDMA Packet Mobile Communication Systems

摘要

Recently, multi-code DS-CDMA packet systems such as High Speed Downlink Packet Access (HSDPA) have been investigated to achieve over 2Mb/s in the mobile radio downlink. A frequency selective fading channel, however, deteriorates the throughput drastically, because it destroys the orthogonality among the multi-codes and causes multiple-access interference (MAI) from the other code channels.
