Joint beamforming for multiuser SCFDE block transmission system in frequency selective MIMO channels
Single carrier frequency domain equalization (SCFDE) joint beamforming in frequency selective multiple input multiple output (MIMO) channels under the multi-user scenario was analyzed.Firstly,the frequency domain beamforming was transformed to a time domain filtering beamforming.By using the time do...

| description | Single carrier frequency domain equalization (SCFDE) joint beamforming in frequency selective multiple input multiple output (MIMO) channels under the multi-user scenario was analyzed.Firstly,the frequency domain beamforming was transformed to a time domain filtering beamforming.By using the time domain model,the signal to interference plus noise(SINR)expression of every receiver at the decision point was shown after the frequency domain minimum mean square error(MMSE)equalization.Under a given quality of service(QoS)constraint of every receiver,the optimal beamforming coefficients minimizing the total transmitted power from all transmitters were found through solving a convex semidefinite programming (SDP) problem relaxed from a nonconvex quadratically constrained quadratic programming(QCQP)problem.Simulation demonstrates that the total transmitted power from all transmitters varies regularly with different settings deployed by the model. |
