A Robust Channel Estimation Scheme for 5G Massive MIMO Systems
( Hindawi Limited , 2019 , Article)Channel state information (CSI) feedback in massive MIMO systems is too large due to large pilot overhead. It is due to the large channel matrix dimension which depends on the number of base station (BS) antennas and ... -
Performance of OFDM with M-QAM modulation and optimal loading over rayleigh fading channels
( IEEE , 2004 , Conference Paper)We present optimum bit and power loading algorithms for orthogonal frequency division multiplexing (OFDM) systems using an M-ary quadrature amplitude modulation (M-QAM) scheme. Several scenarios for the amount of channel ...
