Title
Receive antenna subset selection for time-varying channels using Slepian subspace projections
Abstract
Receive antenna selection (AS) preserves the diversity benefits of multiple antennas with considerable reduction of hardware complexity and costs. We propose a receive AS method for time-varying channels which utilizes low-complexity Slepian subspace projection techniques. The proposed method uses Doppler bandwidth knowledge and takes into account practical limitations such as training, packetization and antenna switching. Results show that the proposed AS method outperforms ideal conventional systems with perfect channel state information (CSI) but no AS at the receiver and AS using the conventional Fourier estimation/prediction method. A closed-form expression for the symbol error probability (SEP) of M-ary phase-shift keying (MPSK) with receive AS is derived.
