Joint beamforming and transmit diversity for WCDMA
- Joint RTO IST and SET Symposium on ‘Smart Antennas’, RTO-MP-119
, 2003
"... The current work develops an efficient scheme to be used for the downlink of a WCDMA network, using transmitter diversity and beamforming. The performances of space-time transmit diversity (STTD) in combination with selective transmit diversity (STD), beamforming (BF) and beam sele ctive transmit di ..."

Joint Beamforming Strategies In Ofdm-Mimo Systems
- in Proc. IEEE Int. Conf. on Acoustics, Speech and Signal Processing (ICASSP 2002
, 2002
"... recently established for several systems such as HIPERLAN/2 and Digital Video and Audio Broadcasting. The success of this modulation is due to the easy implementation of the modulator and demodulator, including the equalization process. Moreover, in last years also increasing interest has been put o ..."

on the study of MultiInput -Multi-Output (MIMO) channels, based on the use of arrays of antennas at both the transmitter and the receiver. In this paper we propose two new and low computational cost joint beamforming strategies for communication systems that combine OFDM and MIMO channels. An asymptotic
Blind Beamforming for Non Gaussian Signals
- IEE Proceedings-F
, 1993
"... This paper considers an application of blind identification to beamforming. The key point is to use estimates of directional vectors rather than resorting to their hypothesized value. By using estimates of the directional vectors obtained via blind identification i.e. without knowing the arrray mani ..."

- IEEE J. Select. Areas Commun
, 2007
"... We consider the downlink of a wireless system where the base-station has M ≥ 1 antennas and K user terminals have one antenna each. We study the weighted rate sum maximization in the case of non-perfect Channel State Information at the Transmitter (CSIT). Some relevant downlink optimization problems ..."

problems, such as the stabilization of the transmission queues under random packet arrivals and the proportional fair scheduling for infinite backlogged systems, can be solved as special cases of the proposed problem. We restrict the transmitter strategy to be based on Gaussian coding and beamform-ing
Multicell interference mitigation with joint beamforming and common message decoding
- IEEE Trans. Commun
, 2011
"... Abstract—Conventional multicell wireless systems operate with out-of-cell interference treated as noise—interference detection is infeasible as intercell interference is typically weak. This paper considers the benefit of designing decodable interference signals by allowing common-private message sp ..."
