The Analysis and Evaluation of Uplink Transmit Diversity Schemes in Multi-User HSUPA System
Chi Zhang, Yongyu Chang, Shuhui Liu, Dacheng Yang · 2011
Transmit diversity can be regarded as a technology in wireless communication in order to enhance the system performance. Some relevant methods of transmit diversity have been presented on the basis of link-level research but do not consider multiple access interference (MAI) existing among users in the uplink of multi-user system. In this paper, we proposed one uplink transmit diversity scheme, which considers the effect of MAI in HSUPA. System-level simulation shows our strategy can degrade the interference level at receiver, save transmit power of user, and make an improvement to system throughput compared with the traditional method which does not consider MAI to some extent.
