Abstract :
Joint design of beamforming and combining vectors for multiple-input multiple-output (MIMO) wireless systems is considered. The proposed approach employs widely-linear (WL) techniques, aimed at providing substantial performance gains over linear ones when the transmitted signal and/or the disturbance exhibit noncircularity features. Computer simulation results assess the claimed performance gains.
