Abstract—Cooperative base station (BS) signaling in multiple-input multiple-output (MIMO) multicell networks has been recently shown to achieve significant gains in system throughput and reliability. However, the promised gains of BS cooperation depend on the assumptions of ...

Abstract—Although recent studies have shown the potential benefits of base station (BS) cooperation technology, existing schemes rely on the assumptions of (i) perfect backbone links between the central network controller (CNC) and the base stations (BSs), and (ii) mobile stations ...

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.
