An iterative BiGAMP-based receiver for coded massive MIMO systems with low-resolution ADCs
《Science China(Information Sciences)》2021年第11期243-244,共2页Yi SUN Ming JIANG Chunming ZHAO 
supported by National Key Research and Development Program of China(Grant No.2018YFB1801103);National Natural Science Foundation of China(Grant No.61771133)。
Dear editor,The hundreds of antennas deployed in massive multipleinput-multiple-output(MIMO) systems lead to an insupportable burden in terms of hardware costs and power consumption. This has motivated the research on...
