Joint transceiver beamforming in MIMO cognitive radio network

open access: yesTongxin xuebao, 2015
An iterative SDP-MMSE algorithm based on semidefinite programs (SDP) and minimum mean squared error (MMSE) was introduced to minimize the total transmit power. And a further approach on the max-min fairness beam-forming was presented.

A PPN-Based Improved QAM-FBMC System With Jointly Optimized Mismatched Prototype Filters

open access: yesIEEE Access
Recently, it is shown that a spectrally-efficient low-complexity quadrature amplitude modulation (QAM) filter-bank multicarrier (FBMC) system can be designed by relaxing the constraints on the time-frequency (TF) product at the transmitter (TX) and the ...

Robust Beamforming via Worst-Case SINR [PDF]

open access: yes, 2008
Minimum variance beamforming, which uses a weight vector that maximizes the signal to interference plus noise ratio (SINR), is often sensitive to estimation error and uncertainty in the parameters, steering vector, and covariance matrix.
