Abstract

This letter investigates the performance of a mixed diversity-spatial multiplexing transmission strategy for multiple input-multiple output (MIMO) networks based on dual code transmission with antenna selection. The wideband code division multiple access (WCDMA) physical layer protocol has been used to demonstrate that for eight transmit and four receive antennas per user, 2.4Mbps more capacity is provided compared to single code spatial multiplexing transmission and 100% code allocation gain, compared to diversity combining and four codes per user.
