CDAT is an advanced version of the coordinated multi-point (CoMP) transmission. Space-time block coded transmit diversity (STBC-TD) for spatial diversity and minimum mean square error filtering combined with singular value decomposition (MMSE-SVD) for multi-user spatial multiplexing are described under the presence of co-channel interference from adjacent macro-cells. Blind selected mapping (blind SLM) which requires no side information transmission is introduced in order to suppress the increased peak-to-average signal power ratio (PAPR) of the transmit signals when CDAT is applied. Some computer simulation results are presented to confirm the effectiveness of CDAT techniques. key words: 5G mobile communications network, distributed antenna network, cooperative signal transmission, space-time block coding, multi-user communication, signal peak suppression received his B.S., M.S. and Ph.D. degrees in engineering from Tohoku University, Sendai Japan, in 2011. He was a Japan Society for the Promotion of Science (JSPS) research fellow from April 2014 to March 2016. Currently, he is with NTT Docomo Inc. His research interests include space-time block coding for mobile communication systems. He was a recipient of 2013 IEICE RCS (Radio Communication Systems) Active Research Award.
