Abstract
We compare the achievable throughput of time division
multiple access (TDMA) multiple-input multiple-output
(MIMO) schemes illustrated in the 3rd Generation
Partnership Project (3GPP) MIMO technical report,
versus the sum-rate capacity of space-time multiple access
(STMA). These schemes have been proposed to improve
the 3GPP high speed downlink packet access (HSDPA)
channel by employing multiple antennas at both the base
station and mobile stations. Our comparisons are
performed in multi-user environments and are conducted
using TDMA such as Qualcomm’s High Data Rate and
HSDPA, which is a simpler technique than STMA.
Furthermore, we present the unified optimal power
allocation strategy for HSDPA MIMO schemes by
exploiting the similarity of multiple antenna systems and
multi-user channel problems.
