We consider transmit antenna subset selection in spatial multiplexing systems. In particular, we propose selection algorithms aiming to minimize the error rate when linear detectors are used at the receiver. Previous work on antenna selection has considered capacity and post-processing SNR selection criteria. However, in this work we consider a geometrical(More)
Power offset is zero-order term in the capacity versus signal-to-noise ratio curve. In this paper, approximate analysis of power offset is presented to describe MIMO system with uniform linear antenna arrays of fixed length. It is assumed that the number of receive antenna is larger than that of transmit antenna. Spatially Correlated MIMO Channel is(More)
