Fast transmit antenna selection algorithms for MIMO systems with fading correlation

Motivated by some properties of the determinant of Hermitian positive definite matrices, this paper develops some fast transmit antenna selection algorithms for MIMO systems, based on instantaneous channel information or channel statistics for a correlated fading channel. The performance of these algorithms is evaluated in terms of both the resulting system capacity and error rate. The novel G-circles method can achieve many advantages over other existing algorithms.
