In this paper, a new scheme is suggested for cooperative beamforming (BF) and relay selection in CR

networks, where a pair of secondary users communicates with each other assisted by some multiple antenna relay nodes. The goal...

error (DM-MMSE) beamforming algorithm. Simulation results

show the superiority of our proposed cooperative beamforming

algorithm regarding the bit error rate (BER) performance and

convergence rate....

In this paper, a new algorithm is proposed for cooperative beamforming, power allocation and relay

selection in the multiple input multiple output (MIMO) Orthogonal Frequency Division Multiple Access (OFDMA) CR systems where a pair of SU...

for cooperative beamforming, power allocation and relay selection in the multiple input multiple output (MIMO) cognitive radio systems where a pair of secondary user communicates with each other assisted by a set of single antenna relay nodes. The objective...
