Abstract
We consider a MIMO system where error-prone feedback from the receiver is used by the transmitter

to select a single optimum antenna to transmit data. Such error-prone feedback is common

in the bandwidth-limited real systems, and is in marked contrast with the idealizations assumed

in the selection literature. We show how the signaling assignment, which maps the antenna indices

to the codewords that are fed back to indicate the index of the best transmit antenna, affects

the performance of transmit antenna selection. The impact is intimately coupled with the receiver

design. We derive approximate closed-form expressions for the average symbol error probability

of QPSK modulated... (More)

of QPSK modulated data in a spatially correlated channel, and then systematically find the optimal

signaling assignment. Performance improvements are demonstrated for different antenna

topologies without introducing any additional redundancy. (Less)
