English abstract:
In this paper the performance of interference alignment is
evaluated for the downlink of 3GPP UMTS LTE via the
Vienna LTE Link Level simulator. Interference alignment
is compared to closed-loop spatial multiplexing, a noncooperative
communication scheme. In order to reduce the
computational complexity of solving the interference alignment
problem for each subcarrier separately, the same precoding
and interference suppression matrices are used for
disjoint subsets of subcarriers. The performance impairment
in terms of average throughput reduction of this approach
is analyzed numerically. Furthermore, the performance
of interference alignment is investigated for realistic
fast-fading channels employing outdated precoding and interference
suppression matrices.
