SVD-based IWFA for next generation wireless MIMO communication
Vinodh Kumar Minchula,G. Sasibhushana Rao 한국통신학회 2018 ICT Express Vol.4 No.3
Point-to-point MIMO systems without channel state information at the transmitter (No CSIT) and with perfect channel state information at the transmitter (Perfect CSIT) were considered for the application of a novel singular-value-decomposition-based (SVD-based) iterative water-filling algorithm (IWFA). The optimal transmit power was computed for Rayleigh fading-based eigenchannels using an estimated iterative water-filling power allocation algorithm to maximize ergodic capacity. The results obtained with the proposed method showed significant improvements in ergodic capacity compared with the average power allocation method.
