Abstract (in Japanese) (See Japanese page) 
(in English) Let us assume that space division multiplexing (SDM) signal without precoding is transmitted at a base station (BS) with a number of antennas to a mobile terminal (MT) with fewer antennas. It will be intractable for the MT to decode the SDM signal by linear space filtering in the case of less degrees of freedom at the MT. Helper MIMO reception can be applied to decode the received SDM signal frame with the enhancement of degrees of freedom at the MT by obtaining other SDM signal frames received at the surrounding MTs with higher-frequency band wireless transmission. In this manuscript, we show the performances of discrete-time coded radio over higher-frequency radio (DTC-RoHR) and discrete-time amplitude RoHR (DTA-RoHR) for a two-antenna source, a single-antenna destination, and three single-antenna helpers.
