English abstract:
In this paper, we report on the results of physical layer
multiple-input-multiple-output High-Speed Downlink
Packet Access (HSDPA) throughput measurements. These
measurements were carried out in two different environments:
1) an alpine valley and 2) a city. In addition to the standard
compliant single- and two-transmit-antenna HSDPA schemes, we
defined and measured a four-transmit-antenna HSDPA scheme
to explore future enhancements of the standard. To analyze the
implementation loss, we introduce the so-called achievable mutual
information and compare it with the actually measured data
throughput. We find that the measured data throughput is far
from the optimal, leaving room for future receiver optimizations.
Furthermore, we find that the achievable mutual information is
far from the channel capacity. Thus, optimizations in the standard
could further improve HSDPA performance.
