Research on compressed sensing of KL domain with limited feedback in MIMO-OFDM system
In order to solve the problem of feedback link overhead in MIMO-OFDM system, and improve the transmission efficiency, a limited feedback method based on KL domain is proposed in this paper. In this method, the state information which is obtained from the channel estimation performed in KL domain sparse at the receiving end. Thereby a small amount of linear measurements are obtained which represents the total channel state information, Then these measurements are fed back to the transmitting end. In the transmitter, the channel state information is reconstructed through orthogonal matching pursuit algorithm. The simulation results show that the proposed limited feedback based on KL (Karhuner-Loeve) domain method can achieve full channel state feedback effect and decreases the overhead in the feedback link.
