Abstract (in Japanese) (See Japanese page) 
(in English) Space-time line code (STLC) is one of the space-time coding schemes in which information symbols are transmitted sequentially across multiple antennas and or time slots. By exploiting both spatial and temporal dimensions, STLC achieves high diversity gain while maintaining efficient data transmission. STLC is typically considered in configurations with a single transmit antenna and multiple receive antennas. When the transmitter has access to full channel state information (CSI), the receiver can decode the signal through linear combining of the received signals without requiring CSI. Motivated by this property, this paper proposes the application of STLC to collaborative terminal multiple-input multiple-output (MIMO) transmission. This approach is expected to reduce the CSI sharing overhead at the terminal side, and we clarify its effectiveness through computer simulations.
