| Popis: | For the transmission technique by a multiple-input multiple-output (MIMO), space division (SD) multiplexing and spatial modulation (SM) have been proposed. However, since they have a trade-off problem between the system performance and the maximum transmission rate, we have proposed the SD-SM-MIMO. SD-SM-MIMO achieves a little computational complexity and a high system performance by the channel ranking and the QR decomposition with M-algorithm maximum likelihood detection (CR-QRM-MLD). By using this system, in this paper, we propose the CR-QRM-MLD for the SD-SM-MIMO with the null modulation which reduces the transmission power and keeps the maximum transmission rate. |
