They may be limited in scope, dependent on human input and send their output to human brains, but they copy, select and recombine the information they handle.
In this paper, a new transmit beamforming scheme with limited feedback is presented in Multiple-Input Single-Output Orthogonal Frequency Division Multiplexing (MISO-OFDM) systems.
In this paper, the impact of channel estimation error on the performance of multiuser Multiple-Input Multiple-Output (MIMO) transmission based on limited feedback information is analyzed.
