Joint transmitter and receiver beamforming

algorithms for uplink multiuser multi-input multi-output

(MIMO) communication systems are proposed in this paper

based on maximizing an utility function, which ...

In this paper, joint transmitter and receiver

beamforming algorithms are proposed for downlink in multiuser

multi-input multi-output (MIMO) communication systems. The

proposed beamforming algorithms ...

In this paper, a new algorithm is proposed for

cooperative beamforming and power allocation (CBPA) in the

downlink of multi-input multi-output (MIMO) cognitive radio

systems. Increasing the efficiency ...

Orthogonal frequency division multiplexing/offset

quadrature amplitude modulation (OFDM/OQAM) based multicarrier

system achieves better spectral efficiency in comparison

with the widely used multicarrier ...

at transceiver. Employing such a deployment, prevents to use of ADC or RF chain in each branch of MIMO system because of power constraints. Thus, Such systems impose to have a hybrid analog/digital precoding/combining architecture. Hence, channel estimation...

Cognitive radio technology can effectively improve spectral efficiency by allowing secondary users to access licensed bands without any harmful interference to primary users. Due to harmful channel effects such as fading, ...

An iterative algorithm is proposed in this paper to

estimate the singular value decomposition (SVD) of multipleinput

multiple-output (MIMO) channel from the received signal.

The proposed algorithm is ...
