| Abstract(in English) | This study presents a low computational design method of MIMO downlink system using large transmit array antenna, which is suitable when the number of receivers is quite small compared with the maximum acceptable value. A large scale array antenna is divided into several subarrays, then each of them is designed, and they are again combined as an array of original construction. Two types of procedures are considered, namely, the transmitter first design, and the receiver first transmitter second approach. Computer simulations show the proposed method achieves significant reduction of computational load with small performance degradation. |
