| Summary: | This paper investigates the effect of link-layer
error mitigation support in MIMO wireless linking systems,
and compares connection approaches between SISO
and MIMO at different BER operating points substantiated
by analysis of captured channels. In particular, this paper
concentrates on a packet-based TDD approach, with a
link-layer error mitigation scheme based on selective-repeat
ARQ of segmented IP packets. Analytical expressions are
derived for transfer efficiency over such a system, and simulation
results presented to verify performance in terms of
application delay experienced by users under various error
conditions. This is repeated for SISO and for three
alternative MIMO connection arrangements. Result show
the degree of improvement available through the incorporation
of link-layer error mitigation based upon the selective
repetition of erroneous sub-IP packets, and in particular
that presenting decomposed MIMO bit-pipes exhibiting
diverse error conditions to the link layer, may be advantageous. |
