In this paper we propose to use multiple precoder codebooks for MIMO systems with limited feedback of precoder and bit loading. One precoder codebook is designed for each bit loading vector in the bit loading codebook as bit loading contains information on the importance of individual subchannels. For each precoder codebook, we incorporate the associated bit loading in codebook design to minimize transmission power based on sequential vector quantization. There is no need of informing thedoi:10.1109/spawc.2013.6612118 dblp:conf/spawc/ChenL13 fatcat:lezwt5han5bvte5nmt3lms5vki
