Abstract
In order to compare low rate error correcting codes to MIMO schemes with transmit
diversity, two systems with the same throughput are compared. A VBLAST MIMO
system with (15; 5) Reed-Solomon coding is compared to an Alamouti MIMO system
with (15; 10) Reed-Solomon coding. The latter is found to perform signi cantly better,
indicating that transmit diversity is a more e ective technique for minimising errors than
reducing the code rate. The Guruswami-Sudan/Koetter-Vardy soft decision decoding
algorithm was implemented to allow decoding beyond the conventional error correcting
bound of RS codes and VBLAST was adapted to provide reliability information.
Analysis is also performed to nd the optimal code rate when using various MIMO
systems.
