The problem of multiuser multiplexing with a
MIMO sub system for each individual user is considered. We
demonstrate that the capacity performance of the null space
based spatial multiplexing schemes can be improved with iterative
power allocation within the iterative design process. We
considered water-filling based local and global power allocation
and demonstrate that both schemes outperform the existing null
space based spatial diversity technique in terms of mean capacity
and outage capacity.
